Purple kush

She couldn’t get the shell off her leaf. I took the dome top off and now she’s getting fresh air and straight light. I turned the lights to 18/6 and I hope it’s not too soon for that? I guess we’ll see. I almost lost her last week. I was fearful of over watering but in such a small container the soil looked wet enough but it wasn’t and she started to starve and curl over. Since I have one shot in the soil I Ph’d water to 6.3 and fed her and she perked up like I have her crack.
