What deficiency is this?

New grower here!

Its week 3-4 flower of my first auto run in 3 gal fabric pots using FFOF. I've been watering when dry every 3-4 days and top dressing with 444 gaia green every 3-4 weeks starting 4 weeks into veg.

The yellowing started at the bottom most fan leaves and smaller leaves and has been working its way up. This started about 1-2 weeks ago.

I have no idea what the problem is and could use some help/advice. Happy to answer any questions about the grow to help narrow it down.

Pictures here under kitchen lights.

Each time I amend with Gaia 444 I add 2 tbsp per pot

A couple days ago I added Lotus 5-10-14 to my amendment for flower adding 2 tbsp per pot
