Hey man they dont look too bad.. A little nute burn on the tips but not bad...Stop using the Miracle Burn, and feed them plan water for a few days and see if it helps..I cant tell about the stocks,(what strain is it?, what light?) but get a gentle breeze blowing over them to strengthen your babies up..

When your plants are that small they need little fertilizer. Also throw away and fertilizer you can buy at home depot. Go online or to a hydroponics store and buy your nutrients there. I use bc grow/boost/bloom and awsome blossom. Your stems should never turn any color besides green (not purple either) purple is ok however on the leaf stems
