It's Easy Bein' Cheesey

1/25 HVAC system at grow room went haywire and the temps in the growing area were 94° when I arrived and plants sustained those temps for 24+ hours. Plant leaves were severely folding up around the edges. In the one days time since they were cooked, the leaves have started to go back to normal. Like an idiot listening to random forum advice, I did not feed these gals or treat the coco with anything other than ph'd water and thus I had developed some nasty purple stems and growth appears to be severely stunted. I have since began feeding and the purple stems are correcting and they are growing again. GSC has been fed and was planted in coco charged with mild nutes and calmag. Definitely know better for next grow. Also, going to back off a little on nutes for GG as she is showing mild signs of nute burn on her tips. 1/27 moved girls into their new home. 4x4x6.5' grow tent with 600w mh and will switch to hps when flowering starts. Theyre in an enclosed patio and air temps have been hitting high 40s at night. I have kinked the exhaust ducting to reduce flow, placed thermostat controlled heat mats, and monitoring temp. RHe has been exceptionally low today at 17% so I added a water tray and rh is climbing back up. If I can't sustain temps, I'll move back inside. Root zone temps are staying at 70° air temps 66°. Adjusted light to avg 43k to 51k lux per plant according to my light meter app. 1/27 fed everyone. Prepped and charged 5th pot, can't decide between Fast Buds WCOG or Dinafem Sour D. 1/28 added a temp controlled/thermostat outlet and plugged in the 6" inline can fan pro 420cfm and set temp to 74°. This thing is brilliant and is working flawlessly. Temps and RH are happy. I have a large oscillating fan blowing 24/7 inside for air movement. Upped nutes and fed to counter yellowing. Gave first dose of great white 1/29 popped a Dinafem auto sour diesel, if it sprouts, it will to far behind these plants. I will start it's own journal. 1/30 plants responding well to increased ppms. Yellowing is going away. Upped ppms from 550 to 700 for this feedingame
