Brown rusty looking spots on my Santa's leaves. I dont know what this is.

These blotches are only on my santa Maria f2's , the THC, Kush and Brainstorm are all looking well. Their all grown in 60/40 mix of soil/prelite and all watered from the bottom as not to nutrient lock the siol. They are all given the same nutrients. Should I give them an iron supplement?. Any Ideas

Actually looks like infestation, like spider mite damage.

Looks to me like either mites as suggested above or a calmag issue.


Some strains are known to heavier in need of Ca or Mg or both.

Looks like a Calcium def to me. If the plants are about 5 - 6 weeks old, that is when is usually shows up.

Give a calcium supplement and see if this helps.
