hey everyone, so a strange thing has been happening and i'm not too sure if i should be worried or not. The roots from my plants seemed to have grown upwards as well this time and they are not even a centimeter underneath the top layer of soil. Whenever i water them i can see thick roots..they are also a greenish colour which i know is not good. I've read that roots being to exposed to light (i'm running a 400 hps) can create problems. So i decided to transplant..although they have more soil ontop of them now its still very close to the surface. Any thoughts?
