Seedsman Speed Auto Stealth Grow

Sunday PH was low, but did not adjust, waited a few hours and it had leveled off. Monday PH was 6.4 with EC 1.4. Added water and nutes to bring everything back to 1.5EC w/ 6.2 PH. Tuesday Do not want to mess with ph too much so im let the plant be to see how things go. Defoliated most of the fans leaves and tiny colas from the 3rd node down on each cola. There are smaller nodes forming near the top of the plant that I will leave alone for now. Wednesday Plant bounced back from defoliation overnight. PH tested at 5.9, EC 1.4. Used RO water and nutes throughout the day to slowly bring PH 6.2 and EC 1.25. Thursday Plants seem healthy with lots of tops. Morning EC was still about 1.2 and PH went to 6.25. Main concern is there are no calyx's forming yet, let alone pistils. Comparing to other grows plants is way behind. May reduce light schedule to 14hrs see if it starts things up. Friday PH tested at 6.25, EC 1.2. Still no calyx formation. Reduced light schedule to 14 hrs. Turned the light off mid day to light stress the plant a little bit. Saturday PH tested at 6.45, EC 1.2. Added water and nutes and left alone for a bit. Eventually went back down to 6.1. Defoliated again.
