How much water do you give when you do water?
You have some really dark leaves, even the most bottom one and cupped..one issue is for sure that the soil underneath is hot, namely with nitrogen. Then the yellowing and what seems like some twisted new growth at the top..an issue with zinc and possibly iron lacking. Those dark leaves can also be too much magnesium, which would explain the lockout of zinc and iron. The excess nitrogen would also hurt sulfur's uptake.
It's hard to judge as i haven't run in true organics, but plants themselves operate the same way with regards to the uptake of nutrients and using them, regardless of medium used to grow them. Elements also interact with each other the same way, just at different ppm/ph levels.
Auto's are picky, and that super soil may be a bit too hot, but it's entering full flower shortly, maybe it'll balance out. It's just with excess nitrogen, and an auto, it can hurt yield significantly.
Plus you're in a fabric pot and only 2 cups of water for a 3 gallon container? 1000 watt mh light, temps good, humidity only 40%, and 2 cups of water? I guess if it works, great! To me, in those conditions, she should be getting at least the 1.5-2L every 3-4 days for now. Something seems off if she's only drinking 2 cups every few days in your setup. Perhaps that's why the droop then..soil does look bone dry, just a thought.
