Nute Burn or Overwater or under lit?

Attached are pictures of my AK 47, been flowering for 5 weeks. Growing in Rockwool, using Ionic Bloom (3-2-6) + a drop of SuperThrive per 5 gal, water phed to 6, bubbled, I water the rockwool twice a day. Flowering under 600 hps (her bottom branches aren't getting any light, could this be the problem?), growroom never more than 80.

The plant is lush on the top, but the bottom leaves are turning yellow then brown.

Any ideas would help so much!

Whoaaaa twice a day!!!! Stop watering it so often or it will suffer from deoxygenation of the rootball and die very soon.

looks like your over watering try just watering once every four days use water and no nutes for a week or 2

I'll do it, but for clarification I thought that hydro systems flooded twice a day. I should be watering them how? whenever they are dry?

You are griwng in rockwool, which needs to be allowed to dry somewhat to oxygenate the roots.
