The top leaves turn yellow on the tips, and the new leaves look a bit weird, like curled up ... I thought of calcium / magnesium deficiency. You confirm ?

That clawing is generally a sign of Nitrogen toxicity, as are burnt tips. I would lay off the nutes and see if that helps. Possibly flush with plain water but it's so mild it will likely correct itself without that.

Looks like nute burn bro. Calmag deficiency makes the leaves go a weird blotchy yellow and rusty spots. Leaves claw up if it's overwatered

Leaf Discoloration - Hopefully Nothing I'm looking to rest my concerns that these removed fan leaves from lower/center canopy are not simply just appearing so due to lack of light and prior plant tie damage. Focus on the yellow/brown discoloration, actual physical damage is accounted for. More details in main post.

The leaves are still curling downwards and inwards. This usually happens once the leaves become older. Although I've searched for the cause of the problem, I still don't understand what's wrong.

orange sherbet crispy leaves. Close to harvest Fastbuds Orange sherbet first grow. I already harvested this plant but I’m curious what the issue was. The leaves were yellow and crispy to the touch. Other leaves looked fine. 2.5oz harvest but it dried really fast(7 days) and now smokes harsh. Don’t want to repeat this mistake.

Leaves hanging down Northern Lights, Autoflower, 6th Grow Week. Some leaves hang down weakly since a few days, especially the upper ones. The weird thing is, that some leaves feel a bit dry, other ones feel normal. The other plant, Critical Auto, looks absolutely fine and healthy.

Light green tops I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.

Yellowing on older fan leaf Hey guys, my photo sour d has some earlier growth showing some yellowing in the center of a few leaves. I fed this plant a foliar spray of cal mag plus way back in the 2nd or 3rd week and it got burned on the leaves but does this look more like a deficiency?
