has it always been in the MG soil?

i would go get, some fox farm soil, super thrive and get some fox farm nutes,
big bloom and tiger bloom and u might as well get the grow big since i am sure
u will do another grow. use the grow big for veg and the other 2 for flowering.
then transplant them in to the fox farm soil (try to knock off the excess MG
stuff before re-potting) then mix the super thrive in with ur water, cuz its
helps with stress, and water them. then after a couple of waters add the nutes
at half dose and work up from there

but thats just me and i am no pro by any stretch of the imagination
