New grower, what is wrong with the leaves?

Discussion in 'Sick Plants and Problems' started by NajaK, May 17, 2023.

  1. Plant looked fine when I went to bed last night. Woke up today to find little spots developing on the bottom leaves. What is causing this? The plant is grown in a tent.

  2. Hi @NajaK

    normally, spots like that happen when the media doesn't have enough calcium (ie. calcium deficiency) or pH isn't good (and plant can't absorb the calcium), but I also noticed this:

    maybe look into that.

    idk what media you are using, what nutes, if any, etc. You may just need to feed some water + calmag solution or possibly increase the calcium nitrate in your nutrients.

    Welcome to the forum.
     
  3. Thanks for the quick response. I will try some calcium and check the ph. Cheers!
     
  4. Look at bottom side of leaf.. look for bugs.

    Ph fluctuations
    Unstable pH values can affect the nutrient intake of your cannabis plants, resulting in brown spots appearing around the middle and lower parts of the leaves of your cannabis plants as a sign of stress.
