    HELP! Leaves Yellow/Brown Spots/ Taco shaped also. UK Sunshine

    First time gurilla growing, Im having a plant with yellow spots/ Brown spots on the leaves

    Can anyone tell me whats going on. Basically just watering no nutrients are added. They are still in small pots.

    Im thinking either spider mites or the plant is now needing nutes?

    Please find images below can give any more info if needed.

    during day light out in the garden pure sunlight

    Over night LED lamps.

    Any help would be greatly appreciated, I thank you for your time.

    Stay high stay friendly!

          You might wanna check the manufacturer's recommendations on that one- seems pretty low. Mine are at 32inches. Flowering I lower them to 18 ish.

        Looks like a calcium deficiency to me. Do a quick search on Calcium(Ca) related deficiencies and compare symptoms. From a glance they look fairly similar. If found out to be, I'd suggest a cal-mag solution for foliage spraying(allowing a quick uptake) following with a root administration.
        Ask questions, take notes, and check your pH regularly. 😌

          Check you’re PH levels. Do you monitor the PH in your water fx ?
          it could be the reason why is showing cal-mag deficiencies.
          some PH fluctuations. If the Ph is on spot - then I agree it could be early stage of a calmag deficiency.
