I am growing 4 super skunk seeds right now under a flouro light... Three of the plans are growing straight up and great. They are about 4 or 5 inches tall right now. One of the plants has fallen over, how do I get the stems to be stronger? Also I have just been giving them water with no chemicals in it, should I start giving them some high acid food? and when should I put them under my hps lights? I feel like an idiot asking all these ?'s but I want to do everything perfect
