Fan leaves turning extremely yellow late flower
Hello. Day 61 of flower, Green Crack 2.0 by Humboldt seed organization. Soil based. All of a sudden all the fan leaves are turning yellow. Trichomes are clear, no exceptions. Is it from finishing or did I mess up watering/nutes in the last couple of weeks? Thanks in advance.

Yellowing tips
Hi, I'm a newbie grower here. I have an autoflower that is nearly weeks old. I have started to notice some yellowing tips on the leaves. I have been feeding it some vitasol and pm13/14 as well as watering every two days. The growing medium is worm casing compost and perlite.

Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

About plants ..
For those who have dealt with nitrogen deficiency, after correcting it, did the affected leaves regain their color, or did they stay the same while only overall plant health improved?

New grower with questions about burnt tips, browning/scrunching leaves and some pale/yellow spots!
I noticed Quick One had issues with burnt tips and discoloration by the end of week 1 and 2, what could've been the issue? Apple Fritter is looking sick, brown spots, what is that? Easy Bud and Quick on have slight yellow/paled spots on their leaves, only 1-2, is that normal?

Leaves turning yellow and dying
I have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

Black tips and spots on the leaves
I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves
