HMMM...dark green leaves....tips clawing...leaves have a 'fake plant' look to them....If these were my plants I would start here...

So, you just transplanted (shock #1 slowed growth) and changed mediums form insta-feed crap into a premium organic soil.(shock #2...nutrient and trace elements could easily be in excess or deficiency... also slowing growth, and possibly causing terminal illness). Change of light cycles (shock #3 also slows growth)...If you top, start training, or transplant again into bigger pots...(shock #4 and/or #5...adding more nutrients to the medium and also slowing growth)....That is a lot of shit to throw at a plant that is already having issues.
If these were my gurlz...I would get the ph dialed in and top dress the soil with some lime. I would not feed at all for a good 3 weeks...the FFOF is hot enough to provide all they need for at least that long. And basically leave them the fuck alone so they will do what they were intended to do. Cultivation is not complicated but growerz are so there are many plants being killed with too much love.
But all of this is just my opinion...make your own choices.
