    spot the problem

    hi everyone, So this is happening to one of my plants.. brown spots. im growing 2 plants that are the same strain and both are feeding from the same reservoir, one is taller then the other and the taller one has these spots on it BUT only in a couple of places closest to the light.. light burn? doesn't look like it to me .. the shorter plant hasn't got a mark on it,
    can someone shed some light? thanks..

    Hi Dave, Have you flushed your plants at all with plain pH'd water? I can't really tell from just the one picture--would like to see the whole plant--but they look very dark green as well. Maybe a 36 hour flush would be good for them. It doesn't look like light burn, I'm thinking nute lockout--hence, I recommend a flush.

          could be two different phenos and the tall one could need more calcium than the short one.

            Dave, the plants look great!!!

            I'm hydro too and my pH mostly stays at 6.0 or under. If you've never flushed your plants, you'll see them breathe a sigh of relief after you do. People usually worry about deficiencies, but we all feed our plants so well that a deficiency is usually only possible because of lockout. I swear by regular flushes--every 2-3 weeks.
