Fox farm soil Fox Farm Nutes 1 gal pots 8 42-watt cfl 3 weeks old not sure of strain The other day I noticed my plants were starting to lose color on the top of the leaves. I had given then nutes for the first time and thought I may have used a little too much. The new growth is what is changing color, so I assumed it wasn't nutrient burn. They aren't really yellow, just a pale green. Looked around the problem page and thought it might be Thrips. I looked and didn't see any bugs or any Thrip poo. Any other ideas? the first two are of the sick one. the last is my healthier plant, but the new growth is a lot lighter green.
