Im growing GDP, my babies jus rooted out of the cubes and i just transported into the 4x4 rockwool cube. i have about 39 clones in their first week under a 1000w mh. temperatures have been 85 highs and 70 low at night. My stems are starting to turn purple. I know that this happens sometimes because of cold, but knowing those tempteratures i dont know if this is the case. Do you guys think it is, or could it jus be a stress related thing because of the transplant for the small cube into the bigger cube?
Thanks in advance.
