i have a few of my seedlings that are 12 days old acting funny its my first grow ph is 6.5 i used crappy soil i think... i used miricle grow moisture control but i dont think thats the problem cuz some of them are fine.. im useing a 400w mh that is 16 inch from them... but any waqys my problems are some of them are starting to turn colors from the shoots like a light green not quite yellow color and a couple are starting to roll there leaves? there not curling down or up there just kinda retarded looking like there rolling them.. ill post pics a lil later but i think the coloration problem is from over watering and a nitro def but i have no idea why those other couple are rolling... the ones that are rolling also have no color problems there a healthy green. any ideas?
