My plants are 14-16" feminized skunk strain under 400 watt met halide in vegging right now. I have them in 2 or 2.5 gal.pots. I already see root tips at the bottom holes of the pots. Should I transplant to a bigger pot or just let them be? what problems will that cause? will it kill them or just stunt growth if roots start coming out the bottom? I still have the whole flowring stage to go...? Any input would be greatly appreciated....Thanks
