Slayah,
I would chill as far as using ferts for now coz your plant is recovering from stress. Here are some links though that may help.

Stick with the cool whites for vegging, those should be ok.

Dont worry about the pearlite this time around, but in future grows make sure you get potting soil thats properly mixed.
DojaDave Reviewed by DojaDave on . plant trouble the leaves on the bottom are becoming yeallow and some areas are brown too, and that yeallowing goes to the top. I ferted it with 2/3 solution a few days ago, all the leaves became droopy too. so is it overwatering or underferting or overferting ? the plant is 1+ month old. oh yes the thing became even worse then I topped it, but I don't think that this is the problem.
