answered grow question 4y ago
it could very well be lack of calcium and magnesium. you can google "comon lack of nutrients cannabis plants", from the examples shown, this seems CalMag deal.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.
I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

Brown spreading spots
Hi there! I found some strange brown spots on my tangerine dream, which are spreading. It looked like a burn, but the ,,burnt“ patches are not crunchy! Do you guys know what it could be?

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistils
So this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.

Why are my leaves getting brown yellow?
My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.

Discoloration and Spots
I'm still not sure if this is a deficiency or some sort of burn. It's definitely spreading a bit more, and I'm unsure if there's time left to address it in the grow. Video of full plant in week.
