Looks like a magnesium deficiency to me. Some of the pictures from last week it looks like there is some interveinal yellowing and the deficiency has progressed. Epsom salts will help fix the issue. Happy growing!!!

Having an issue where the leaves are spotting Brown. Iām adding cal-mag and am not having this issue on any other plants except for this one. I thought it could be from misting the air with a spray but stopped that for a while and it is still continuing.Week 3

Brown Spots on LeavesIām noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I donāt think Iām overwatering. It could be the nutrients but would like input!Leaves. Color - Dark-brown

Little browinish/beige dots near leaf veinsI noticed some weird little browinish/beige dots near the veins of some leaves, mostly the upper/center ones, those exposed to the light. I checked for bugs everywhere, even with the jewel loupe, and I haven't see one. What can it be? Maybe heat/light stress?Week 11
