does the leaf feel leathery? It was probably under watered or over watered at one point and the ph was slightly off. Nothing to worry about if it's just the bottom fan leaf. Just re adjust next time and you will be fine.

End of Cycle or something to be afraid
Hi everyone, I think the brown leaves just reflect the end of cycle (WG started flushing 4 days ago, DSD33 today). I don't see signs of mold or something rotting, brown leaves do not detach, both plants show already some amber trichomes. What do you think?

Bruising or nute problem?
I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.

Copper spots
I noticed these copper spots and leaf tips about a week ago, it doesn’t seem to be progressing too fast. The plants otherwise seem to be healthy but what is the issue? Magnesium Def?

What’s causing some of the leaves to look like this? Is it a deficiency or excess? I was watering with 1000 ppm, but I saw some burnt tips and dark green color on the leaves, so I gradually lowered it to 500 ppm, and today I noticed those spots (the drained water is at 750 ppm) (coco and perlite).

Is this bud rot?
I found strange purple/dark brow discoloration on one of buds and surrounding leaves. It could be caused by bad supercropp of the cola, or I am thinking bud rot. What do you think, should I harvest immediately, or am I stressing too much? RH is 50-60%, but the box is cramped.

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Do I have to worry?
Only on one leaf of one plant. Is this some fungus or virus? It looks a bit like coffee rust, but I couldn't find anything else like it. How should I proceed? Thanks in advance!
