i get light burn with the tallest of the plants hitting the light, i use floresents to start plants. If your plants get burned it would be from where they touch the bulb(imo), the lower leaves really look like when nute burned. i also use the ocean forest mix, and yes...i dont fert till four weeks, but when you do start....quarter strength nutes should be enough. Did your soil dry out bad or get hot? just my thots....they couldnt be root bound yet could they?
Glad to hear they are looking better tho.
Amazing how they bounce back.....i just found a ground squirel in my garden cage, little bugger was having a hard time finding the front door. Hope he dosent like MJ for lunch!
