Coco with advanced nutrients. PH???
- Thread starter Newgrow31
- Start date
It should work that way depending on what water your starting with. My Last house the city water was 150ppm. And came out a bit around 7 ph. The sensi coco line with ph perfect came out just right. My new house has a well the sensi coco still brought me real close to 5.8, BUT I had to switch to RO water for other reasons. Sensi coco works as it should with the RO water.
Over all I'm very happy with the ease of use of AN, I have considered switching because as I've scaled up the cost has become quite high. But as of now I'm still hesitant to switch.

A bit late but wondering if you ever switched? I've used AN pH perfect Bloom, Micro, & Grow with Coco Loco mix for multiple grows now and found it works really well. The only issue I've found is that there is not instructions for a different feeding schedule once in the flower stage and the nitrogen is too high once a few weeks into flower. Do you use something else or change the dose after switching to flower. I've been slowly decreasing the ratios of the 3 part AN and supplementing with a flower stacker starting week 2 flower which seems to be working but I think my bud density may be lacking as a result. I've never had a pH issue so I'm hesitant to start a different regimen. Any thoughts or advice? Thanks!
Still haven't switched, just started buying larger containers and price isn't as bad.
I don't use the three part, but are you sure there isn't a different schedule for flower? I used to use it in dwc and thought for sure you lowered the grow and upped the bloom. But it's been so long and they have changed things some sense then.
I like using the AN sensi coco 2 part (actually 4 bottles cause 2 grow and 2 bloom). I use it with coco loco with great results. But honestly I think cutting the coco loco with mothers earth coco+perilite 1 bag to 1 bag is the way to go.
I've been hitting some really nice numbers and quality that way.
I think tweaking that formula on the 3 part would prob work just fine though.
What kind of light are you using? And what's are your temps? Fresh air intake? Just thinking of other reasons for lack of density. If they look healthy it's not always the feed causing issues.

Thanks so much for the reply!
I considered this and played around with it my first grow by reducing Grow and increasing Bloom equally in my first grow of this strain but still ended up decreasing the ratio after noticing a slight N burn. After looking more closely, both the Bloom and Grow have a total of 1% Nitrogen with the Micro at 2% and they are recommended at a 1-1-1 ratio. The Bloom has 3 different types whereas the Grow just Nitrate Nitrogen so maybe the plant doesn't process them the same way but honestly, I have no idea. With my current regimen, my plant looks great (no burn, yellowing, etc.) all the way up until flushing. I use a AN flawless finish for about a week and straight water for the last week.
My current light is a Phlizon 1500w dimmable light for my 2'x4' tent with a 6in in line fan at the top for exhaust with a small fan circulating right at about light level and another small oscillating fan that sits on the ground. My temps range from about 68 F to 75 F and my humidity has been about 40 RH for the bulk of the flower stage (last grow it was a bit higher being in the midwest during summer) but overall the bud structure was the same regardless. I considered there may be another issue and I'm starting to think bad genetics may be playing a part. TBH, the seed came from a friend so I'm not sure where they were purchased from.
Does the Sensi AN give you instructions for flower feeding and if not what changes do you make and when? I may give it a try since you've had good luck with it. At the very least, maybe I can narrow down my bud density issue.
I hear when running led you should run higher temps. Do you know how many actual watts it is?
The sensi has a set of 2 grow bottles and a set of 2 bloom bottles. So only use grow for veg and bloom for flower.
Genetics do play a big role, but light intensity is also a big factor in dense flowers.

That sounds so much more simple. Probably going to give the Sensei a try.
The power draw is about 200 watts but it seems to be very bright. Haven't tested how many lumens or PPFD personally but from the manufacturing specs... it should have a PPFD value of 992 umol/m2s which should be more than enough.
My very first grow from this seed (purple punch) was in a smaller tent with a Mars Hydro TS 600w during the summer so temps were regularly around 80-85F with the lights on. Same density issue
. I just started 2 new strains and are growing them in the same tent, conditions, and feeding regimen. Hopefully I'll be able to rule out or confirm genetics as the issue.Thanks so much for the input and advice!

Hi....I am new to this forum (I am in Toronto, Canada) and your post caught my attention. I am also using Advanced Nutrients (pH perfect) with Coco Coir as a medium & with the AutoPot system. My issue(s) with the AN is that the pH typically settles out between 6.3-6.5 The ideal pH range for plants grown in coco is 5.6-5.9 so that raises the question........Does the pH need to be adjusted down to get into this optimum range? I have been adjusting it down but don't really know if that is good or bad practice. Also, most people I have spoken to on the subject of AN all say that the recommended dosage levels are too high and need to be reduced. I am using 75% of the recommended dosage on the AN feeding calculator on their website.
My other concern is that I am getting a slight browning at the edges of some leaves....see picture
Here is a summaryt of what I am growing currently........
Strain: Girl Scout Cookies
Medium: Coco Coir
Nutrients: Advanced Nutrients (using at 75% of the recommended nutrient schedule)
Lights: Optic Slim 600H
Indoor grow tent 4ft x 4ft
Currently in week 6 of Flowering
Current EC.... 2.0-2.2
pH range 5.6-5.9

I had this issue using AN Micro, Grow, Bloom in flower. They loved it while I'm veg but I was forced to lower it gradually after the switch. AN has another called Sensi that is also pH perfect that's a user here told me about. There's 2 types, one just for coco coir that have a differ formula for veg and bloom. Just picked up the bloom for my next grow and my girls are seeming to like it much better for the flowering stage. Hope this helps!

Great info.......thanks a lot...........that makes perfect sense. You are spot on with no issues in Veg and then it all goes a bit sideways in Flower. So I will definitely try the it. Am i correct is saying it is these two?..........Sensi Coco Bloom A&B and Sensi Coco Grow A&B
Last question.............are you using the full strength (100%) as per the Advanced Nutrients feeding calculator?
By the way, I did reduce the conc in flower earlier this week to 50%............fingers crossed it will help

Should fall around 6.2 ive run it at just that in coco. Might want to drop a hair. You can use ph up and down with it. Ph perfect isnt exacly perfect it just falls in a range useable in most medias.

Advanced nutrients will fall short on calmag in coco but thats almost anything in coco youll need calmag. An falls short on potassium in flower.

Thanks for the insight.........On the CalMag, what dosage & timing would you recommend?
Leon727272

Yep...…agreed. I get a fairly consistent pH reading on the AN of 6.2-6.3 & I always bring it down under 6.0
I been using AN sensi coco grow and bloom for years. When I had good tap water 150ppm or less I didn’t need cal mag. I still did pretty good without cal mag when I went to RO water (moved to a house with well). Recently though I have been using sensi cal and plants seem to like having the extra a couple times a week.
People talk shit on AN but I have such great results with it, I’m honestly afraid to switch,lol. I hit great numbers per light, get good feedback on quality all the time.I also found that if I drive down state to a big city I can buy the large bottles of nutes for a much better price than buy multiple gallon bottles locally.
lately it seems there has been a shortage on sensi coco so sometimes I use the Conniesour coco instead and it seems to give about the same results.
also I never adjust PH on the AN I usually am Around 5.8-6.2 and just leave it alone. When I first started using ph perfect I tried adjusting it and felt like the plants were showing signs of ph being off. So I left it alone and they seemed to like that better. Could have just been a coincidence but I haven’t ph since with no issues what so ever.
I have never reach the full dose on the bottle and I push plants pretty hard with intense light and c02. Ppm meter on 700 scale I usually feed veg 550-800 depending on light intensity and plant age. For flower I water every day and feed between 850-1100 ppm in beginning thru peak of flower then back off to 600-900 for last bit of flower.
I do use big bud coco after week 2 until I start flush. And bud igniter a few times during the first 2 weeks of flower. Other than cal mag that’s only additives I use atm. Tried a lot over the years and these just work best for me.

Good summary on AN................MUCH APPRECIATED

When i started i swore by AN. Stuff works great but when you get to feeding 100 plants with it it hits pocket hard hard. I switched out tried many different lines found much cheaper alternatives. But you will grow nice plants with what you have. Run the 6.2 then drop a lil in flower and bump calmag and k. I had to run 6 ml per gal calmag with an in coco.
Yeah the sensi line is for coco i think it has added cal and mag already. But i ran reg 3 part there were times i was adding 5-6 ml per gallon calmag on top the 3 part. But not every feed. Only if i saw lightening in color coming Id add calimagic. Hard flower is when theyd want more than 2-3 ml.

Yep those are the ones! I start out at very low dosages for my cuttings/seedlings and gradually up the dose over the first 3 weeks or so and I also always use either just water or low dosage (25% or less) for about a week any time I do any major defoliation or repotting to reduce the stress of the change. Other than that my plants seem to love the 4mL/L suggested dose and I was able to switch straight to full dose from veg to flower.
And I agree with Alpachen. I have not had to adjust my pH since starting this nute system. Stays right about 5.8-6. One thing to note is I do only use filtered water for my plants so that may have something to do with it too. You can get an under the sink filter for about $50-70 that lasts up to 2 years on Amazon and the replacement filters are only $20-30. Makes watering multiple plants much easier.
Hope the lower dosage helps! The first time this issue happened it got better but the plant still looked pretty sad by harvest. Thankfully my buds and sugar leaves were unscathed so still turned out ok.

Thanks for all the info. That's very helpful. I did get a good filter for my water..........makes a big difference for sure (can't taste the chlorine anymore either). I've only got 3 weeks of flower left and then a week of flushing so hopefully the 50% reduction in the nutrients will salvage the plants, albeit, they are not looking bad currently.........time will tell, I suppose.
