White Rhino yellowing and AK-48 not looking to big.

[Blammo300]

Currently there are 2 Nirvana White Rhinos and 1 AK-48 at 37 days flowering. The first pic is of the WR which has had issues with yellowing for at least 3 weeks now. The cola sizes on the WR are looking good though. The AK-48 has had green fan leaves throughout the grow but is growing bud much slower then the WR plants.

Using 70% FFOF and 30% Light Warrior, used Tiger Bloom, Big Bloom at half strength every watering. Have used Epsom salts in almost every watering as well at about 1 tablesoon. They are under a 600w light with temps ranging 70F at night and 90F at the hottest but usually sits at 85F.

epsom salts in every water sounds like too much, i only put it in mine about 3 times from clone to finish. cant help u much with the rest however there is a form to fill in for plant problems.

good luck

Looks to me like you cut out the N too early. Not alot you can do about that now seeing as most of the fan leaves have died.

Make sure to keep giving them a moderate dose of grow ferts up until halfway through flowering next time, along with your bloom nutes. I've noticed if I don't do this I end up in the same situation as you....with underdeveloped buds and no more leaves to pump them up any more.
Your AK48 looks ok...the buds look a little small but overall it looks healthy from what I can see. You might just have a sativa pheno that may take a while longer to finish.

Hopefully someone else can chime in here and give you better advice.

good luck & peace

did you use dolomite lime??? it looks like a PH imbalance or what GB said above^(major N lack-age) the whole epsom salt thing every day is also not a good way to go. Like Gb said once your down this path its really not much you can do except either flush em really hard and dose em up with half grow nutes and half bloom nutes(but its pretty late at this stage), and you could get some cal mag and throw that in as well Or you could jsut ride it out and keep doing what your doing.unfortuantely when a plant gets tot his stage its very hard to tell IMO, because it oculd be a few things and its very tough to diagnose it perfectly without actually knowing more history and event hen its not a gaurantee anyone will know the magical answer...
------------------->Either way make sure to get some pulverized lime(i keep telling people this as i went through the same things and didnt listen when i was told. GET DOLOMITE LIME AND USE IT AND I PROMISE THAT WILL GO AWAY NEXT GROW(considering you dont over water/feed etc)

I do have some Dolomite lime powder but I forgot to use it when I transplanted them into 2 gallon pots. Last night I transplanted the WR's into 3 gallon pots and used about a tablespoon of dolomite lime per gallon of soil. I watered them last night with plain distilled water, no nutes, just 10 drops of Superthrive.

So there isnt much I can do at this point for the White Rhinos, I couldnt add some grow big into next watering? How much will this yellowing affect yield and potency?

Next time I should use FF grow big half way through flowering?

Yes... and then mix the veg and bloom ferts and 'ween' the plants off of the veg ferts.

you can still give them a small dose of veg now. Even better, get some fish emulsion and add a little to your flowering fert. they'll green up quickly. You don't want them to green up too much, so use a few drops only. the Ak-48 is definitely slower flowering (it's more sativa-dominant) than the Rhino, don't worry.
