Need some Coco help...pretty please with sugar on top?

Let me start with a little backstory...
I started growing a few years ago...tried hydro for the first 2 and while the plants finished, the meager smoke I got off of half dead looking plants was disheartening, so I got some soil...and have finished quite a few plants very very successfully in soil, but for cost effective-ness I wanted to try coco...so I picked some up with some canna A+B...Now this time around I know I gave not overfertilized...I have been using 5 drops of A and 5 drops of B at a time just to make sure I don't kill my plants, but soon after moving a clone, and a larger plant into the coco they both look very very light...they look underfertilized, but I don't want to keep adding more if that isn't the issue...I mean I know 5 drops isn't really much, but I have overferted too many times...lol. I never trust deficiencies...they usually turn out to be overages in the end...

So here are some pics of my plant, so please only people with some coco experience please please help me out...do I nute at next watering...
The roots on this little clone are doing awesome..already poking out the bottom of the tiny pot, and I just moved it 4 days ago...so it is technically growing, but it just looks so pale...the leaves feel healthy, and you can't even really tell that great in the pics, but the bottom leaves are super light greenish edging on yellow...there are some splash spots on the top of the plant and I know what those are...
If you look close you can see the nice green of the top of the plant, but when I move that out of the way you see the horror underneath...my temps are good, and I feel pretty confident I am not overwatering...although I guess that is always a possibility...also both plants moved to coco do look a little droopy and water logged, could it be from the transplant from soil to coco...it doesn't look like transplant shock, but more like perhaps the differences between coco and soil are just too great for one plant to conquer in one grow cycle...is it bad to start in soil and then switch to coco...? I bet it messes up the pH...which I did flush my coco repeatedly with 5.5-6 pH water before planting in it...anyway here are the pics and I will stop my rambling...

Ohh and I started a seed straight in the coco and it seems to be doing just great...



So...as you can see this clone is doing well on top...but underneath is a different story.

I use coco exclusively, though I have no experience with your nutes. I looked them up and it appears you aren't using enough. You want 3tsp per gallon of each A and B. Also make sure you shake well.

I find better success with a ph of 6.3. If the Ph goes to 5.8 I get more burns.


Also going from soil to coco isn't a great idea, with coco you are supplying all of the nutes while soil has nutes in it.

I know I am using way less than the recommended strength...I just figured with the soil and what not in there they could still get some from the soil they were in originally...so would you say that you think it is simple deficiency? I have no burns so far...and I don't want to get any now by messing it up...lol. They have only been in the coco for a few days and they are already super yellow, which is just not what I was expecting...but I guess since coco has no nutes in it at all, I do need to add a little more than what i have been...I just have hydro nitrogen burn PTSD...I freak out when I use synthetic nutes at all, just because I have effed up so many plants back in my hydro days...I am kind of already regrettinghaving gotten the coco and the nutes...I would just go get some soil, but these coco nutes aren't the cheapest and i just bought them to try switching to coco and I feel like I haven't tried enough yet..lol.

Also another question I have...
How dry am I supposed to let this stuff get in between watering?

I love coco. I never have to guess about nutrients because I am the one supplying them. I would definitely say it is time for a full feed. I water every 2 days, the pots should get really light in that time. I feed very frequently, 2 consecutive then one plain water, but I also flush frequently. Also you don't need nutrients specifically for coco, I use fox farms Grow Big, Tiger Bloom, and Big Bloom.

Ok..I totally wondered if putting the soil and rootball in the coco would be alright...and I thought and I thought, and I pondered...and then I just transplanted from soil to coco...because coco also says it is good to mix into soil...so I don't see why inner soil and outer coco would be too awful...And...you say the most perfect pH is aroud 6 ish? The canna coco says on it for best results to have the pH between 5.5-6.2, and i am trying super super hard to make sure that is where it gets to...I use the color liquid stuff, so nothing is exact, but I can gauge it pretty close with the colors...lol. After a few years of using the stuff...lol. Anyway thanks for your help. I just want to make super super sure that this is a deficiency and not something else before I give it anything...You have no idea how many posts I look at and usually answer everyday where people say that they have this deficiency or that deficiency and it is 9.8 times out of 10 it is not a deficiency but an overage. So I am always skeptical of deficiencies, because you rarely actually see them if you are giving any kind of base nutes...even just a little...we give plants way way more than they need to grow and look nice...what I am saying is that MJ really doesn't need all the nutes we think she does...and i find my plants grow a million times better if I give them less, so I am just afraid to give a normal dose...since normal or recommended doses have been nothing but trouble anytime I have tried them...
I get better results with less, but I might be over- lessing it here...
I just need more opinions...
Do I in fact need to add more nutes, and if so do i have to wait for this stuff to dry out, or should I go ahead and use some stuff?

Well damn...I just figured that the canna coco nutes would be the best to use for coco...I have a lot of other stuff I am not afraid to use that says it can be used in coco...I mean you can't really beat how fast the roots have grown in just days, but the yellowing is definitely troubling to me.

So...I bucked up and added one whole teaspoon per gallon to both ailing plants today, and both look even more yellow, so that is not it...I am thinking it is in fact over water, and ya know what? They do both look a little droopy...so...Apparently I have overwatered them...dammit man, so today I made it worse...lol. At least it isn't a big deal...just going to leave them alone to til they start to look nice and thirsty. lol

Truth be told it looks as if you may have caused a nutrition lock by moving from soil to coco the percentage change may have varied to much and caused a lock out of one or more nutes namely mg and cal after you let them dry out a little you may want to only feed Phed water just to flush out and equal out the nutrition balance between the soil and the coco just a thought have used coco before but soil is best for my taste

Well I gave them both plain water their first water after the initial only water to water them in....so...I don't think that is the issue, but thanks for the reply...the leaves are yellowing out, with no burns or curls...the leaves are droopy...I was too worried about the coco nutes to really look at my plant and see what the issue was...
If I had calmed down and took a big deep breath I would have been alright and realized what the problem was...but after feeding with no success the issue is clear.

I have had plants look great in a passive hydro/soil mix...I ran out of soil and I had a couple clones needing to be moved out of solo's into pots, but was out of soil, so anyway I am watering these plants, I do this when in solo by setting the solo cup on top of another cup filled with water...and bottom water them til they are in larger pots..anyway I was lazy and let them sit overnight and most of the next day on the counter and when I went to get them they and a marigold sitting beside them had grown roots into the cups below...so I just started changing the water at least once everyday...and they did just fine..and hydro and soil are supposed to need totally different pH and all that...

Of course I repotted them after a few weeks in the double cup setup, but they looked just fine and unstressed for weeks growing that way...

What is the ph level now

I use the color chart liquid
and it is the same color going in and coming out which is the yellow orange of around 6...lol.

is there some other way to check what the pH is? but I don't see anything that makes me think pH...

With the changes to hydro type setup means the ph should be lower 5.5-5.8

Well the bottle of nutes say they do best between 5.5 and 6.5...so I guess you are allowed a little more drift than plain old hydro...lol. but the Ph never changes...it is absolutely not the issue...the issue is that I was worried to start using the coco for fear that it would kill my plants, so when I started using it I stopped being the awesome plant grower I have become, and went back to being nooberriffic....so I didn't realize they just had a little overwatering going on...not to mention the plant in question was a clone just a week before moving it...so, it's going to be looking a little off isn't it? But now all plants in coco are doing well...the only difference between coco and soil is the pH of the water...so no issues...

Ok i read your first post not evey thing else let me start by saying coco is pritty much hydro that you can hand water, small plants might not need water every day but later on you will be wanting to water with nutes every day(I water till i get some run off some people dont and they claim to do fine) and about once a week i water with Plain PH'd water to get ride of salt build up.


Edit: I got a old grow you can check in my sig i didnt water like i am now and you can see i ran into some probs but watering every day with nutes seems to make the growth that much faster also i didn't water with plain PH'd water as much witch was my major cause of problems i think

Hi There.

Would like to offer some advice based on my experience.

-Are you able to measure EC or ppm? If so, Do you know the ppm of your source water?
-If not, i would recommend it, it is an asset.

-So depending on that, I start seedlings with a 150 ppm water source, then add calmag until 200ppm and equal amounts of A+B to 400 ppm or so, then a roots product at 25% strength if you have.

-I PH my water at 6.0 in early veg, 5.8 in veg and early flower, 6.0 in mid flower and to 5.7 near the end. (Prefer it more alkaline when they need the phosphorus)

-Whenever feeding, I try to keep your ppms constant throughout and when necessary, increase them steadily (typically range is 400ppm - 900ppm throughout the cycle).

-I never 'flush' or feed without any nutes but ensure adequate run-off when feeding. I carefully monitor them, am proactive and try to react quickly when required.
If this happens, I dont wait for medium to dry out, and feed what I feel is best at that time.

-I water based on personal feel, strain and weight. Gauge how heavy the container is after watering, then when its about 40-50% its original weight, water again.

Well, I always water til run off and then some everytime I water of give nutes...I don't usually give just water, unless the plants look like they would benefit from it...the ppm of my source water is 76...I then add 1 tsp Canna Coco A and 1 tsp B and everything is going right along, although I haven't checked the after nute ppm I know it is much less than the recommended...and it is better to have wayyy less, than even a little bit too much...

As for the watering, I think I have it now...but some plants are different...I have a few different strains going simultaneously and they all like pretty different things...they all look really different too though, so pretty easy to remember who is who...one doesn't want to be watered til the pot is light like a bag of perlite...I am soon going to try it in the coco...it was a huge fail in hydro...but it might so well in the coco, since I now know it doesn't like nutes at all really...no nitrogen...the plant grows slow, but if you give it nitrogen the leaves curl and the top foliage starts yellowing and the bottom leaves burn...I have had her in soil for a good long time and learned pretty much what she likes, so she might do well in coco...due to the absence of nutes...she gets all she needs from the tap as far as I can tell...I only hinder her in my quest to do my best...so I gave up, and she flourished...anyway I am just ranting on and on..

Waiting on the mail yall!
