Normal or start of foxtailing?

I am in the last half of flower stage. 80 days approx from germinating. Starting to see chunky addon growth and new white pistols. Thought it might be light stress but readings are in the 750-800 range at the top of the canopy and temps are 70-75 humidity rages from 45-55. Could it just be a last ditch effort to catch pollen? Or something I should change?

I say you’re in a bind on first pic.
Second looks like you can manage to keep them happy long enough to pull through flower.
First pic id say atleast 3 weeks till ready second you may be able to get away with less …
These are autoflowers correct?
