PH Problems - Extreme Yellowing - Suggestions

they are just limp. im trying to mist them a couple times a day and keep the humidity above 30 but its at 25 right now with a temp of 83, lights are a foot away because i want some stretch.

i really want to make this work but soil is so much easier that i've been considering transplanting.

wheres the screw im suppsed to tighten???

ok well i just checked on it and it is doing a lot better. the root mass has tripled in size, i will post pictures, and i think that root rot was actually the issue. i am continuing to clean the rotted roots out so it doesnt spread but the plant is really bouncing back. i will post pictures tonight.

the yellowing isnt completely gone but i think once i start feeding it again it will go away.

It looks like the old growth is nitrate deficincy, and the new growth is zink or iron deficincy. You can go th the pet store and get a ph test kit and ph up and down. It works 4 me. If your ph is off it will lock out nutrients.

Here's what she looks like now

The roots are a little dark because I just fed with liquid karma (black as coal), but the system is very very healthy and I'm very optimistic.

Any suggestions on when I should start flowering? I want to go now but I think every bit of yellow should be gone before I do. Any advice?

I don't want to jinx myself but I think I might have a handle on this hydro thing...
