Its not working because your ph is out, its like filling a bucket with a hole in it you get nowhere. Make sure waterings/feedings are 6.5 in future and also in veg stage(most important) so the plants start flowering deep green from top to bottom. Make sure temps are under 80 I can see some foxtailing.

ph stays at 6.5 temps around 82 i think ice has a genetic predisposition for foxtailing iv grown it before and my other lady is directly under the light..
no fox tailing there

spex420......yellowing of the leaves during the final stages of flower is not uncommon. The plant is putting all its energy into fattening up those beautiful buds. I've followed several grows where the grower jumped through hoops to get the plant healthy looking again, and it's a losing battle because you're fighting nature.
How are the trich's looking?

Looks like and Iron deficiency too me...probably caused by feeding high P bloom nutes.
Iron
Iron is an important component of plant enzyme systems for electron transport to carry electrons during photosynthesis and terminal respiration. It is a catalyst for chlorophyll production and is required for nitrate and sulfate reduction and assimilation.
Iron (Fe) deficiency
Pronounced interveinal chlorosis similar to that caused by magnesium deficiency but on the younger leaves.

Your statement is simply not true...cannabis plant can, and should be, as healthy and green at harvest as they were the day they where flipped too flower.
Again the so called bloom nutes(way too much P and not near enough N)being the main cause for the typical 'yellow late in flower' plants.

I stand corrected......I've been told by people I respect that the yellowing is the plant's last phase of bloom. My own grows I had yellowing similar to the photos.

your both wrong but your both right in a way
lilroach yes its not uncommon for a plant to turn yellow during the final weeks of flower but thats the fan leaves at the bottom of the plant not the top
alex yes a plant should be as health and green at harvest as they were they day of switch but but it is not uncommon like you said with the bloom nutes the the plant sucking all the stored sugars in the fan leaves if you do get a yellow leaf or two its not something to worry about
on the other hand yellowing burning leaves at the tops are not common

Well then I guess your plants are not as happy as they could be...
