here is your answer,how about posting everything you do & see if someone can figure it out? since you are cloning hydro,you need to know PH,temps, feeding of the mother before taking a clone,light type,rooting hormone used ect.
Thnx. I have big bang growing now. I have taken 1 cutting off her and she was the first to root. And she rooted good. I was jus gonna flower that strain but may jus keep her around if she roots fastI've cloned 16 Big Bang and all besides one made it. Took about two weeks. I used a heated propagator.
The one didn't make it because I knocked it and moved it away from the rockwool.
all sounds goodPh between 5.5 and 6.0. Mothers in DWC(wondering if that might be a prob as its always got nitrogen in her.res temp is at 22.....
