I'm new to plants so bare with me......I'll give some info regarding my setup first.
140Gal freshwater, Pressurized CO2, UV sterlizer, Undergravel heat, flourite subtrate, t5 lighting (200+ watts).
I've had this tank setup for 3 weeks now and my plants are starting to wilt. I don't have the names of all of them, but the sword's leaves are becoming transluscent and I'm afraid something with the water is drastically wrong.
I tested PH 6.77, GH 1deg, KH 1deg, phosphate 0 and waiting on an Iron test kit.
Any assistance would be greatly appreciated.
