They're in 707 roots organic soil under the new growers choice e-720. Light is 720watts about 12 inches from canopy. I gave them straight ph water till after the stretch since it's new soil and just started feeding. I've been doing feed water feed. Using fox farm nutes with 3ml calimagic with RO water

Fox farm bloom nutes? I also used 50/50 bloom veg nutes until around week 3 flower and then switched to full bloom and tons of it

Looks like P deficiency to me, but I'm no expert at diagnosing deficiencies.

I would top dress with a balanced blend.

Something like this
www.horizenhydroponics.com

Organically Done Balance (3-3-3) (8lb)

An organic product formulated to provide a balance of organic nutrients for general soil amendment and plant fertilization. Derived from 100% organic, non-toxic ingredients, this is the perfect fertilizer blend for your overall gardening requirements.
www.horizenhydroponics.com www.horizenhydroponics.com

That has a balanced amount of NPK and should have some calcium and magnesium in it. Every plant ive ever grown has tended to kill of its biggest fan leaves at the start-middle of flower.

This looks like K deficiency.

Final weeks of flower
