    Default brown splotches on fan leaves

    I've got several plants, outdoors in 45 gal smart pots, that have developed brown splotches on the leaves. As this is only the third time I have grown outdoors, and am relatively inexperianced, I wonder if this is something I should be concerned about?

    Soil is a 80% compost / 20 worm castings mix that I got at the local worm farm. I added blood and bone meal, azomite, lime and organic cow poop to the mix. They have been outside since mid may.

    Any help is appreciated

    It looks like a PH imbalance. Have you checked the PH levels of your substrate mix? I had similar problems once with a plant I grew using a store bought organic mixture. The fan leaves would get brown spots on them, turn yellow and eventually drop. As it turns out, my substrate's ph level was at 7.4, much too high for MJ.

    thats a thought that hadn't occured to me, thanks I'll check it out. I was worried that it might be some kind of fungus or something.

    No its been composting for about 4 months, Although I did think that maybe it could have been a contributing factor. Last year I didn't use any and had no problems. Maybe it is to hot for the, not much I can do about that now though.
