Ideally, you take clones from a plant in its vegetative stage. And ideally it will be a mature plant with alternating nodes... this is usually 21 days or older (from seed).
So I have a few clones and there from previous female clone etc. i can still stress these bitches out make em Hermies.. Is this what you saying Ohio. (because so far so good and i would like not to jinks my naive streak)?
Yes. Plants don't neccessarily start out as hermies, flickering lights, uneven lighting/dark periods, any type of stress really can cause them to go over. This gets worse when you use feminised seed.
this fellow grower has been a real tool to me. cost me a lot of my time. i think it would be hella funny to sell him a batch of 40 male clones. set him back a couple weeks. good thing i'm a very nice guy. still think it would be a good burn. but i'm nice..... yeah, but....... no stop....... it would be so funny... stop now.... hehehehehehehe
