Tomorrow they will be 4 weeks old and only 1 plant is drooping badly. On week 3 they were perfect 100% so I did a water change and added full strength Fox Farm grow big according to week 3 of the Fox Farm feeding schedule. The next morning when I was checking the PH I noticed some discoloration (browning) on the roots, so I added a little more H202 and kept a close eye on the plants for nute burn (which I did not see).Yesterday morning I noticed the bigger plant in the back (#1) was drooping badly (see pics below), and the new growth on top looks a little yellow. Also the lower leaves have brown spots on them also now with some yellowing. So far this is only happening to one plant in the tote, and I'm not sure what to do. I think I should do another water change and run only plain water in with h2o2, but I'm really not sure.
I'm using a 400 watt MH light and I'm keeping it about 22'' away from the tops of the plants. If you need any additional info please ask, I'll be checking back often as I can.tyAny help will be greatly appreciated, thank you for your time!
Yep! I bet it is. I never used HID lights before, always used CFL's. So I never had this problem before, but yes I bet light is seeping through the tote or net pods or both. I don't see any algae growing in side the tote, only the brown stuff on the roots. I just placed an order with HTG and I bought some of that 6 mil black & white poly. I heard it was the best to keep light and heat out of my tote! Hope it gets here soon. And no problem on the rep dude, if someone tries to help me out, that's the least I can do for them!
