So i have been having a hell of a time watering this girl. My fault for putting her into too big of a pot with damp soil in the beginning. I have pretty much stopped watering her and will let her dry out some.
I am using coconut water as my nutrients (Old friend told me it works well). I took a fresh coconut, ripped the meat out of it and blended it with purified water. Then i feed my plants. I also moved the lights to 24in. a few days ago.
they are looking more or less ok, considering... coconut water is not a nutrient and your 'soil' should be much more soil much less rocks and whatnot, get at least some gardening soil for house plants and they'll be fine ;)
