Clone Help

I have a clone perma frost. it looks ok but is not growing much.

growing in Blackgold coco belnd. Added a tsp of lime per gal of soil.
nutes are rockwool magic A and B with added cal/mag
ph is 5.4-5.8
light 100w clf. 6500k
The water up take is very slow. I have 3 other strains growing in the same set up. It gets water once every 3 or 4 time the others do. Any help or comments would be great.

It looks nice.I smoked some bud called permafrost a while back that was supposedly from a Colorado dispensary,It was a great strain I haven't had any for a while I need to find/grow some.

It look ok's to me. But I can't figure out why it's growing so slow. It went into dirt. So to speak. Feb 18th. Don't know if this one will get big enough to be a mom. I hope it does. It's great smoke.

Looks nute burnt. Did you fertilize it after you planted in the new pot?
