    I'm 6.5 weeks into flowering, leaves started acting all gnarly, some browning and the tips raising up. Nothing has changed from start to present, other than nutes. schedule. Not sure if its a chemical burn or some sort of nute def. I was battling mildew back in week 2-3, but I have used it on 5 others and this ones the only one doing this. Any suggestions?

    42days 12/12
    600w HPS
    day temps 79-84
    night temps 72-75
    RH% 28-40
    Coco

    whats your pHes at?

    it looks more like a magnesium deficiency, but it could be a P def. too.

    coco is suppose to be flushed every three weeks... thats your problem.. flush

    your coco is holding salts thats causing the problems... flush and watch what happens... its all explained in asked's tutorial
