Flower Week #5 Two Cheese, Two Dr. Grinspoon & A Big Bang Could Critique

[NoFrostyHairedWhiteMen]

Here are my crops entering the home stretch. They are five weeks since the switch to 12/12. The seeds were dropped on September 9. The cheese #1 is 41 inches high. They are being grown in soil inside a 3gal smart pot. The tent is 5x5x8 and it houses three Advanced Platinum P300 LED, two exhaust fans, a carbon filter, and two oscillating fans that strive to keep a temp of 75f and a RH of 35% or lower.

One of the cheese plants, the tall one, has the leaf tips clawing downward and its driving me nuts, so any feedback on any of the plants would be much appreciated. thanks

I think the 3 gal pot may not be large enough for a plant of that size. It's probably too late to up-pot, but @Emilya would know for sure.

The downward clawing and the tip damage on that long running sativa I think is combining with a bit of a lighter coloration at the top of the plant to indicate that this is a potassium deficiency, as well as maybe a bit of a reaction to the 3 gal containers. Smart pots are amazing though, and transplanting this late in the bloom process is just asking for trouble, when it really isn't going to help the roots expand out any more at this point in the game. You didn't say anything about what you are feeding these girls, but I would give them more bloom nutes, specifically heavy PK finishing nutes and I think you can get ahead of this.

That is kind of frustrating because the guy at the local grow shop talked me out of the 5 gallon ones. He said I didnt need that big of a footprint. Oh well

Here is what I have been feeding them. Although with three different strains going at once not all of them have agreed with the regime as much as some others.

Per gallon Distilled Water:
A
Botanicare Cal Mag Plus (1ml-3.5ml)
Fox Farm's Big Bloom 10ml
For Farms Tiger Bloom 3 ml
A little drop of Molasses

Water PH-- 6.3-6.5
B
Cal-Mag 2.5ml
Big Bloom 10ml
Mo;lasses

Ph- (6.5-6.65)
The schedule is A then B.

Fox Farms Bembe every other week 3ml
Soil is 80% fox Farms Forest 20% Perlite
Have been adding Mykos mycorrhizae every month to top-dressing consisting of perlite

I started with General Hydroponics FloraNova 7-4-10 in veg but switched to the Fox Farms late veg. Should I go back to it since it seems to be what a potassium deficient plant would need?
