You are experiencing progressive potassium deficiency. Light nitrogen and heavy potassium are phosphorus in flowering. Good luck🌱

Dark spots starting after feeding. Concern? CalMag, first time feeding with more nutes, so it might be nute burn yea but is it a concern. It started moments after watering, or that's when i noticed it. On a few leaves. Earlier on i cut lower buds and did some defoliation

I have a few brown spots and slight yellowing on a couple of my 3 finger leaves and even some on a 5 finger (#2). It seems to be getting worse every day. I have done a lot of research to find out what it could be but am very confused. Any ideas? Pictures from 2 different days.

Ugly leaves
So, guys.. I asked a question here, like 3 days ago, about some leaves. I think I have found out what has happened. Mold ignition, but very few, at the root. Have already medicated. Do you think this is a mold symtomn? Cheers!

Fertilizer burn or something else?
Hey fam. Plant seemed fine a few days ago besides a mag deficiency. Decided to foliar spray cal mag at half strength a few times. Now there are brown patches and leaves/stems are curling down like they’ve been overwatered. Too much cal mag? Burn? Something else? Thanks!

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.
