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.

Late Flowering Stage Deficiency or Nutrient Burn
I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.

Burnt and drying leaves
Any idea what I might have done wrong on the sick mothman maybe nutrient lock or overwatered? It was the only plant without drainage hole and stayed pretty soaked as I was out of town for 3 days. Any advice is appreciated!

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.

Brown spot on leaves
I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?

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!
