yeah, wait a few week`s in the mean time get a nice bigger pot, with a lot of nice drain holes in the bottom, I prefer plastic or grow bag`s not ceramic
and add about 20% perlite, when watering, water til you get a bit of run off and then give it time to dry out a bit, MJ don't like to stand in wet soil all the time (hence the perlite and good drain hole`s)
can you add a normal household CFL bulb above it maybe ? for extra light doing the evening
