The Autoflower mix!

This week was LST week! Every couple days I’ve been readjusting the low stress training, creating loads new tops. Growth has been explosive, can’t quite believe how quickly they’re growing. - pH is anywhere between 6.3 - 6.8, usually close to 6.5. - each girl given about 1L of water every few days, letting the pots get dry and light to be picked up. Had outside temperatures of 40 degrees Celsius, had a frozen salt water 5L bottle in the tent on the hottest days. Tent got to 36 degrees at one point, but the girls didn’t seem to care. No visible signs of heat stress and they’re still growing like little rockets. Bought some molasses the other day and gave them a little. Should I wait till flower until they have any more? Or can the house benefit from it throughout the grow cycle?
