thanks for the advice stonies, the RH is probably the issue, its a PC grow, just to start my girls before they head to the green house for the season. There's no fan and there was a lot of perspiration on the walls of the PC, I was just confused on why the one would look like that but the rest look great. No worries tho, I topped the plant and installed a fan this morning. They will be outside in a few days, i'm sure she will be fine.
