4 Autos In A Micro Tent...Again!

Coming from a bad week last week, this one for a bit worse. However they seem to be back on track. I think a combination of things caused this but cant be sure. This is my first coco/soil attempt so still learning. First and main issue I think is that i was overwatering with a ph that was a bit too high. My second contribution was the temps being too low coming into the tent along with the cold water I was feeding it. Have lowered the ph of each feed to 6 and am warming the water to room temp prior to feeding. Outside temps have got warmer and more favourable. Tangerine dream(bottom right) has perked up and taken on some colour in the leaves. Sticky Beast(too right) has perked up and also taken on some colour. Runtz(top left) is still growing slowly and leaves very yellow. Strawberry Pie (bottom left) is doing fine as she is in just soil. Topped her this week too. Decided to not top the sticky beast as she was already having a hard time so just going with lst. Hope to try and get them all fully happy again but i already know ive kinda ruined the most crucial part so fingers crossed they bounce back good enough to still get 1z per plant! Thanks for checking out my grow
