Plants do not change sex to create a balance, lol. (nice try though) It would happen in our growrooms too, were that true.

Are other growers having the same problems with the strain?

When you say you put them outside...is there a street light or cars going by at night with their lights on? Growing outdoors, you still need to keep 'em away from unnatural light sources. Especially in flower. :thumbsup:

Any other signs of stress, (dropping leaves, stunting, excessive stretch, yellowing, splotching...) and finally...do the males still show calyx's and pistils?
