can be a cal mag deficiency, but before check your ph (has to be something like 5.8) and the power of your light (too close/ too much power etc)

I think it was a cal mag and everything else too. I believe I was just under feeding them. Thanks for the help

Anyone know what would cause the bottom leaves to look like that? Growth seems quite okay as the plant with no leaf defficiencies hasnt caught up to the one that does, just did a good flush on them so hopefully that sorts it.

discovered some brown dots on the lower fan leaves. Should I worry? Not enough nuts? I'm giving my ppp auto BioBizz grow& bloom 0.75 ml/L and I'm feeding 2 L about twice a week. What ur opinion. ? The rest of the plant looks healthy.

Brown spots due to light height?
Brown spots on a few leaves close to the light that had yet to be super cropped to control height. Not noted on lower leaves. Temps/humidity OK, no changes in nutrients. Thinking this could be from being too close to the lights, but would appreciate some expert feedback. Thanks!

Nutrient problem?
Hi growers not sure what this is as it's only on a few leaves but a few brown spots have appeared and I have quite a few purple stems, don't no if it's a strain trait or if it's phos deficiency or something else, any advice would be welcome, growing in live organic soil.

Same strain, different color leaves.
Why my plants have leaves with different colors (one is darker) when they are the same strain? Both grew with the same fertilizers and while they had issues in early veg. they recovered but developed quite differently! It's the phenotype? Or the issues in early veg. caused this?
