Yes, it's quite common for cannabis plants to develop yellow leaves during the later stages of flowering, especially around the 8-week mark. This can happen for a few reasons, many of which are normal and not necessarily a cause for concern.

Curling leaves upwards, intervienal chlorosis, appears to be mag deficiency to me.

It's normal for the plant to start getting yellow leaves as it's consuming its nutrients, beautiful plant.

What could happen? Low temperatures? Over-fertilization? Or lack of nutrients? Please help, it's the only leaf on the whole plant that looks like this.

To solve the problem of leaves, we did not notice any difference with an ec of 0.8 and 1.4. (group separated 2 weeks ago) :/ Any propositions? In hydroponics is it common for you to use power roots, green sensation, cannazym or the hydro A&B product really enough? Thank's

Hi, anybody know what the problem is with this plant? The top leaves are becoming yellow/white from the inside out. Also the leaves have a different shape. The plant is in open soil and I give her water and sometimes some veg nutrients. Thanks in advance. (Last picture)

Color amarillento en cotiledones
The Purple Lemonade #1, which is the slowest plant in the grow, shows a yellow area on the cotyledons and the first two leaves. Is this something important or relevant? I had to remove the seed shell from this seed because it sprouted but wouldn't open...

Organic peat control
I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Why are leaves yellow?
As shown in the photos, I find yellow leaves of Northern Lights Auto. Until yesterday she has been growing in good health, but now her leaves look drooping and some of them yellow. Also she does not drink water. Why do you think it is? (deficit of nutrients?)

Leaves yellowing and curling
Leaves seem to be yellowing and curling upwards. Is this under watering or a deeper issue such as nitrogen deficiency?

Yellow leaves,
I am feeding these plants all the same nutrients. Canna aqua vega and a 1ml/l calmag with a ph of 6.2 So I was wondering why this is happening. The RH is about 50-60 and temp 28°C. Thanks fellow growers

Is this normal?
Hi fellow gromies, my girl is coming into week ten, everything looks great buds fattening etc. But one leaf has drastically changed colour, I know this happens towards end of flowering. But its just the one so far is this ok? Or should I be worried?

Leaves fading and dying, started from bottom but spreading
I’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.
