Sick Lady

Brand noob to Aero/Sprinklerponics. Home made rig, bubbler in bottom, pump and sprinklers are mediocre but work. Vegged with GH nutes at 30-15-15, grew like nothing I've ever seen. 18" tall 18 nodes unknown asian strain.

Went to 30-30-30 for transition, flowered showing female only and then turned light green, stopped growing, drooped all leaves and large ones started drying up. No yellowing, whole plant just lost all color and did nothing. Dumped, flushed (floracleen), and went to clean water. Ph good whole time, 5.5-6.0, res temps-65 to 75 usually 70/72 with 400w HPS (fan ventilated) light on. H2o2 most of the grow for root rot. Managable. 8 on, 16 off. No change for a week. Thought it was nitrogen tox, or def and or too little light. Went to 12/12, and Lucas formula, 0-8-16. A little better, growing slowly but can't get any color into them. Small runt in foreground and closeups same strain, looked just as bad. Now better. Unknown sativa in same rig got stretchy but is flowering pretty good, although not much better than the ones in soil, but did not wilt or turn light green at all, just slowed down.
Still alot to learn. Any ideas? If it's nitrogen def, how can Lucas formula be used?

I tried to upload photos, unsuccesful.

O.K. This was a bad case of root rot upon transfer to flower. Showed up like a cal/mag deficiency and death. H2o2 wouldn't keep up. Added calmag and no change. Found Hygrozyme. Never seen anything like it. The infected roots ran off into the res and became food and the roots grew back in a week and a half! Nice and white!!In the middle of the flower cycle!!! The tall sativa never even looked sick. Previous pics show how bad the other one was. Threw out mystery seeds from one bag and got two different strains and a lot of variation. Cloned the two good ones. One is very indica and prone to root rot. The other is quite sativa but still skunky and is less prone to root rot and grows fast. These pics were taken a couple days ago. Going to try cycling the pump. Maybe that will help the root problem. Watching res temps now too.
Lucas formula rocks!!!! Hygrozyme super rocks!!!!!!!

Good info thank you!
