Spots on leaves
Growstickanswered grow question 3y ago
It looks like a minor calcium deficiency. A bit of Cal-Mag will sort it. Biobizz do their own one if you want to keep using their brand.

this is a classic :P
it develops on 2 opposite leaves, they are often the biggest, just a bit of cal mag and you'll solve it....

leafs with brown spots and olders become yellow and curledI'm trying to figure out what is the problem with the growing of my plant.
The upper leafs are quite normal, even if they tend to bend downwards.
The old leafs start with brown spots and then they become yellow and curled on the peaks.
Please help me to understand what's going on

Brown spots and yellowingWhat do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.

Burned upper leaf edgesHi!
Dark spots appeared on some upper leaves overnight.
I don't think this is the cause, but I did a pretty heavy defoliation the day before.
the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish.
what could this be?
