    HELP! I think I’ve got a problem. First grow. Leaf spots?

    I topped them yesterday. Today I noticed a few leaves with these spots. I’m clueless. A few weeks ago I overfed but that’s been corrected. Any ideas?

    Looks like white powder mildew thick foilage way to much N. Defoliate would help with mildew and flush with plain water. Make sure plants are drying out before you water.

      hard to tell under those lights. A picture under more natural light may help.

    Tell more about your growing medium.
    your PH leves.
    what nutrients you fed them. For example

    hard to make a diagnosis with these things.

    Do you maintain a proper PH level?


      To me it looks like whatever you had on your hands was transferred on to your leave when you topped it yesterday.

        Ok. I defoliated a lot yesterday when I topped. I took off a few bottom nodes and many fan leaves as well. These spots weren't there then. I’m pretty sure. There was already some tips burnt from a few weeks ago. I also increased the ppms from around 250 to 325 for this week starting yesterday. I’ve been feeding everyday with runoff being around 160 for the bigger plant and 250 for the smaller one. I started feeding daily because when I waited a few days to do it the runoff would be really high (like 550) and that’s how they got burned (I think). I’m using coco and perlite mix with cal-mag, advanced nutrients 3-part and RO water. PH is 5.8-5.9.

          I know you’ve already received some good advice below but if you don’t see results by adding more Cal-Mag I would suggest adjusting your pH up to 6.1-6.2 for at least 1 or 2 feeding per week. I always aim for 6.0 in Coco and try to let it drift up to 6.1-6.2. Having said that my situation is different than yours in that I feed in a recirculating flood and drain system and you are feeding drain to waste. In your case just alternating the pH once or twice a week can make all the difference.

        From the pictures I would say a slightly nute burn. Some of the tips on the leaves are burned a little bit.
        the PH should be on spot when growing in coco

          Yup I see it too - ease up on your watering - you'll be doing your roots and plant a big favor if you let it dry out and get some air to the roots.
          Plant will return the favor.

          Exactly, less is more

        I think it’s a cal mag deficiency. I increased the amount I fed today from 1.5ml per gallon to 2.5ml. Maybe I should add more but I’m pretty sure they weren’t getting enough.

          Just add some ever time you water - I have cal mag in every water feeding I give, never seen a toxicity from a cal-mag to be honest

        I cannot see the spots clearly in the picture. What is the PH of your water or your soil? This looks like nute burn. This looks or Manganese deficiency. There could be a couple of factors. First, your Water PH level should be between 6.0 and 7.0 for soil. You must keep it between these numbers to avoid nutrient lockup. Similar symptoms could also mean too much Iron. I would probably recommend giving it good flushing, then give it more ph and less Nitra. And please don't overfed your plant and always make drainage holes at the bottom of your pot.
