So this is my first real grow, and I think I might have run in to an issue :/. The first issue is I have rooted my clones into 6" rockwool cubes, and without growing more than an inch from their original height they have already rooted through to the bottom of the cubes, and I have nowhere for the roots to go! I was expecting them to break through the bottom once they were ready to be transferred to my aeroponic system but it seems they are a little over eager, what should I do? They still have at least 2 feet to grow before I even consider transferring them to the system but the roots are hauling ass outta there. The other issue is the rockwool is starting to turn black on top, is this something I need to worry about? Thanks for any help you can offer |
