    Default Do you know what's wrong with these leaves?

    Using AN 3-part, B-52, Liquid Karma, Cal-Mag (maybe not enough???) I'm using RO water, but I'm only adding half of what is suggested because the label says if I'm using AN 3-part I won't need cal/mag (even when using RO water). I suspect this is incorrect, and any advice would be appreciated.

    Running RDWC using LED's. Temp/RH/PH all good.

    Check out the picts:

    Thank you all! P1000481.jpgP1000482.jpgP1000484.jpgP1000491.jpgP1000492.jpgP1000493.jpgP1000494.jpgP1000495.jpgP1000496.jpgP1000499.jpgP1000501.jpgP1000502.jpg

    Break away from society, it's a trap designed to keep the poor looking for riches, the rich looking for luxury, and the luxuries looking for their next fix.
