Converting promix pot to dwc

i have a mainlined plant that has been vegging for 2 months and just wouldnt grow well. Same conditions as sisters but this runt wont go. Anyways i decided to wash the promix off as best i could and experiment with a dwc bubbler. Root mass was pretty shitty for the age of plant. I added some rhizoblast and am hoping for some root growth. It is a ww from seed.

Good luck with the move she looks to have taken it well thus far.
