First Ever Grow 1/2lb Bakerstreet -Tweed

Stretched 70% from flip, hopefully slows down as not much height left before its too close to the lights. I have her tied to both sides of the tent and its taking all the square footage possible. Also, drinking lots more - gallon+ a day and the soil is drying out an inch down, and lifting (carefully she's ties off!) the pot is lighter. I lowered the nutrients because of the increased watering, only feeding every second day and lowered the ml/gal to avoid nutrient burn issues (few tips showed tiny burn last week). Have defoliate further to keep the focus on the top buds and have beeter air movement. The temperature management has become a chore (gets hot and I need to cool the garage where the tent is and open the tent). I an monitor the temp remotely but I've started slowly shifting the light schedule later to avoid the mid day heat with the lights being on. Shifting early would be better but I'm not getting up at the crack of dawn to water - I'm not a real farmer here. Finally, noticed what seems like roots coming out and down from where a trimmed the lowest leaves? I'll google and then ask a question - don't think it's a problem itself but might might be a sign of other trouble (could I be root bound in 7 gal pot?)
