So man you are going gr8.Just be patient.Do not overwater ..Water it with no nuttirients at the star for 2 weeks .......i suggest you cause is closet
start the 12/12 when they are a little bellow the half of the closet....
and cut any part of the leaves that is yellow or something like that cause it goes and to the other parts of plant so its better just to cut
I say you this with my experience.....
Be patient ....
