thanks um u say 4 foot oh shit i have it in my draws about 3 half foot im doing 17on 7 off lights is that bad?Well I see red stems on the fan leaves... sometimes this can be the strain but most of the time
it means your plant is stressing from temp's. I would get a thermometer and see what you got going on.
Is it on 12/12 yet? I would transplant into a 5 gallon bucket... or pot if you want to pay the extra cash.
Depends on how much space you have for your grow room too I guess.
When my plants are budding they need to be feed about every other day but make sure the soil is drying atleast 2 inches deep before you water.
If its not on 12/12 youll want to do it now... 2 1/2 feet its going to be around 4-6 feet when its done.
