Im not sure but i thinki got a root problem. My plants are growing fine. they look ok, but the roots dont seem to be growing. My plants are 4 weeks old. They were started in 1" rockwool,
I have them in 3" net pots with hydrotron. The plants are all about 7" to 8" tall. they were topped at the 5th or 6th nod, and now have three nods on each branch. All the lower branches have been trimed away. All that being said the roots are NOT growing out the bottem of the net cups. The few that do are dying, I think. There is no smell or slime just no roots, Is this right?
