Couple weeks into bloom
Organic re amended soil, compost, Coco coir
Unconventional farmer ferments
(Carrot, squash, banana) for bloom
Alfalfa and fish for veg.
Calphos from fish bone meal and oyster shells.
I've been liberally feeding the bloom ferments at the recommended 4T per gallon, using the call phos with more caution.. They are hooked up to blumats with r/o water in the reservoir..
I hope I didn't forget anything..
Yellowing from the top down... My book says sulfur but then goes on to say that this shouldn't happen with soil if only rarely.. The seed did this too, this is the first run of the clones..

Hey Al, what up? How about:
Phosphorous deficiency. 1st picture shows yellowing new growth, immobile element problem, and 2nd picture is classic phos. deficient leaves, red stems too.. Probably locked out from wet medium or crazy PH from all that stuff you're giving her, that's probably why your bone meal is doing diddly. Also oyster shell needs to breakdown completely before giving up it's phosphorus otherwise it might continue to absorb phosphorus, which could be another reason for your phosphor problems though I would think a PH lockout is what's going on.

Doing well, hope you are too Fran! Thanks for the reply. That was totally educational! I'll turn down the blumats and lay off the ferments. The oyster shell and fish bone meal are ground up with a mortal and pestle mixed with apple cider vinegar and then I put it all into a jar with more vinegar to extract. 5 parts vinegar to 1 part pulverized bone/oyster to make the cal phos and I just added that to the hand feed water at 1tsp/gallon at the beginning of bloom. Thanks again!

Agreed! if its not locked out, its just not getting enough.
Hey everybody, just woke up to this.
This is my vanilla Kush on her 87th day of VEG. I've been wanting to switch her over to flower but I want to switch her over to flower when she is her healthiest!! I only Vegged her for so long so I could hope to get a huge Yield In the future. Any input on what the deficiencies or lockout or any information that can obtain to her situation is greatly appreciated.
Temp: 78° doesn't pass 80° lowest is 70°
Rez temps always cool switching water bottles every few hours
Techna flora nutrients at 1/2 strength (the recipe for success)
Humidity is always around 26 -35%. Hard to always bring this up.
Normally the PH stays between 5.7 and 6.1 but lately for about the past 2-3 days the PH drops to 5ish to upper 4's every 3 hours and I don't know why.
Unfortunately no PPM meter. I want to get one but don't have the funds for a fancy one. Maybe a $20 one but don't even know of one reliable enough. Once again thanks for any input!!

You really need to get a good EC/PPM meter. Your plants will thank you!!!
pH drops could be a number of things. Your plants have a nice root structure but the top half is having some serious issues.
Your plant could be underfed. pH could be dropping from the plants taking up nutrients causing a loss of buffering. 1/2 strength for a plant that size is probably a bit too low.
But first and foremost....lets get a PPM pen....even if its a cheap one and we can go from there!
Thank you very much

I need help to distinguish of I have a nutrient deficiency or burn. Its only a couple plants out of 8. I have a soil coco coir mix. They are 10 days old. I'm using a very light mix of sensi grow part a and b. I'm also using voodoo juice, tarantula, piranha, b52. The new growth has a weird yellowing of the tips and just noticed small reddish spots on just 1. Not sure of the strain but it's feminized. Growing slow. The second plant is yellowish in the middle of the plant. New growth has kinda burnt tips. 3rd plant is a paleish green in the middle and new growth but the outer half of the big leaves are green. Also.....I'm using a pretty big led grow light about 3 ft. From the floor and the plants are in solo cups.

Do you think 7 bottles of plant food have something to do with it?

As you know, nutrient burn and deficiency are on opposite ends of the spectrum. What EC are you feeding? If you are going on the "light" side chances are you are under feeding. You are using a lot of expensive "additives". The A and B products are supplying 90% of the plant's food. We need to get those values right before adding the extras.
Any pictures?

A lot of those bottles are extracts and bacteria/fungi. The real nutrition is coming from the A and B. What EC do you get after you mix only A and B?

Me personally? 600 ppm at 8 ml per gallon, ill add an enzyme after that and call it a day for the first 4 weeks of flower while barley increasing my base till week 5 then ill keep it at that till finish.

I don't have a ppm meter. I put 1.5ml of the base nuts in a 1.75L bottle. And 3 ml of the addatives

I couldn't get the lighting right to see the pale green color in the middle

Well it's the root mass tribe your sapose to use them for the first 2 weeks of veg and bloom.

Ha they sure have a lot of people fooled
I didnt realize you had seedlings. If you have soil and coco mixed....give pH'd water and microbes only. Let the plant figure out what life's all about before hitting her with any nutrients (especially when you have soil).

Hey everyone need some help. I am sad to say that I had no idea what buffering coco coir was untill I just read it here.
I had started 8 seeds in a soil and coco coir mix. I peeled the coco coir off the brick and just mixed it with soil and added a lil water so it would expand. That's it. Now one of my plants is purple around the whole edge of the fan leaves.......is this too much calcium??? I tried to get pictures and could not get the lighting right.......long story short I broke my phone. Any help would be get much apreciated
