I have two seedlings at day 16. One started getting dark spots in between the veins on the leaves, starting from the tip and moving in. Now the second is starting it. Both have leaves curling up. When it was just the tip i tried cutting it off, since cutting leaves was ok to do with the clones i assumed it was ok for these. Ph is 5.5, ppm around 400 or less, temps cool, humidity low, rez water clear. I had an issue with cloudy water so i cleaned everything and refilled with distilled water instead of tap. I had too many nutes at 800 ppm so i lowered it. Since cleaning and refilling, the bad one has gotten worse and the good one has started to do the same. Internet said mg deficiency or light burn. T5 was 6 inches away but is now 12. Flora trio with about two cups h2o2 is whats in there now. Looks like im gonna lose the bad one can anyone help me save the good one?
