Sorry, I suppose I should have mentioned they are still vegging and he won't be flipping the light back until they are between 13 - 15 inches.

Hi Everybody,

A friend of mine has plants in his grow room started from clones (one of which I gave to him) that range from 8 to 10 inches tall and have started to pre-flower under 18 hrs of light. His plants are pure sativa except for the land race indica I gave him, and all of them are doing it. I have never seen this happen, and was wondering if anybody has ever had this happen to them. I find it weird that even the clone I gave him is doing it, and mine have never showed pre-flowers until after I flip the light. Could it be stess, or a environmental thing?? I'm completely stumped.

Thank you in advance for any response!
