dark green leaves, stunted growth!

[LeeroySlim]

i have tansplanted 10 clones from rockwool cubes to coco. i have them in my greenhouse in a part where its not direct light. in 2 weeks they have not grown at all the shoots seem to be poping out and then they dont open and expand into leaves.

i feed them twice a day 1/4 nutes canna coco, seaweed and superthrive
ph should be aruond 5.8 but its been about 6.5.

4 of the 6 clones are like this, the other 6 are doing really well already 1ft tall.

the last 2 pics are of the same strain a couple weeks before harvest.

any1 got any ideas whats wrong?

thanx mate +rep ill give that a go

maybe too much nitrogen...too much nitrogen will give you dark green leaves, with a shiny look to them

ill flush a few times before i transplant then

 

[produce2smoke]

keep us updated, because im having some problems with nitrogen and would like to see whats goin on with your plant...thanks in advance

ok no worries mate, i just started to flush them, ill transplant then in a couple days and see how i go

how much time is the plant in that same pot ? i thought the 2 weeks u refered was 2 weeks from transplant or something , if it is much time in the same pot and 2 weeks that stoped growing then yes definatelly is rootbound and putiing extra ferts to give it a push led to that , the best u cando is transplant w/o flush , just water enough as in transplants and everything will be fine
