This is my first attempt at cloning myself, ive watched numerous videos on it and figured out my own way using other peoples methods. So I basically presoaked my rockwool cubes for a little over an hour in water that was ph to 5.6 or so, I made the 45 degree angle cut, then I shaved off the skin at the bottom, and cut it down the middle for more surface area to root, dipped in clone-x gel and placed in the rockwool after I squeezed it out, its been about 11 or 12 days and I just don't think they are going to make it, they are yellowing and no root growth is visable yet, can anyone tell me if this is normal? do they look like they are going to die? and now apparently the website isn't letting me upload pictures so I will try to add some later.
