I'm having the same trouble with my clones.....the mother is big, bushy and beautiful....and budding, but the three clones are all stunted. I've transplanted them and they all have great root structure, but every one of them are no more than three inches tall.
One of the clones I'm trying to flower, thinking maybe that will start it growing outward.
The other two I have under vegetation, but they are not growing outward like the parent plant has.

I'm using Flor in the veg stage(18-6), and 1000 watt HPS for flowering.(12-12)

I'm also looking to solve this problem. Any advise??
CmeSmoke Reviewed by CmeSmoke on . questions about growing okay, this is the second time growing and the first time having total control. so i'm doing okay except one of the clones is stunted for about 2 months its under 5 inch. tall....WTF??? tried many things including adding huge amts. of N(which didn't kill it yet, did a nice chem burn though, but it's okay i've leached it and all is okay) giving more light for several days, and repotted to bigger container. The other clones are thriving and one is up to 16in in the same size pot. HELP?? Rating: 5
