I Have 6 sugar shack plants and a few sweet island skunk just freshly trasplanted from my clone chamber and all the sugar shack plants seem to have yellowing tops and the first few sets of leaves are turning yellow and growing distorted also. i added worm castings to the mix this time around and heard that it can be to heavy for the roots to breathe??. i fed with General Hydro. ferts last night thinkin it was a deficiency but i have no change so far today. im in sunshine #4 soil mixed around 30% with worm castings i made myself. temps around 75 and humidity at 60% useing a 400w MH lamp. i was wondering if anyone has any clue what this could be?? I will post pictures tonight if i can figure out how. it takes ages on this computer... Thanx for your Assistance sorry bout no pics i will try to get on it.
