From the looks of it, it looks like a leaf dying from not getting enough light which is completely normal. Hopefully, I answered your question and remember " Happy Growing".

Hey guys, I just wanna ask, all girls except one looking bright green almost a bit yellow. And only one is dark green. Someone has experience with this strain? I read about a yellow albino but I think it isn‘t that yellow :) Would be really thankful for your ideas. Thanks guy

Why is one leaf yellow AND shiny?
Plant has one leaf that is yellow on one side, and shiny/dark and curling up on the other side? From what I've read those are 2 opposing issues (light burn or nitrogen deficiency/or toxicity) the others are pretty much uniform, Could this be from getting water droplets on leaves?

Do I have an Iron Deficiency, if so How do I increase Iron levels (Already using Calmag)
I think I have an iron deficiency. New Growth is appearing yellow. HYDRO Rain water - (20ppm) PPM 750-900 (just upped) Canna Aqua A+B Calmag (0.35ml/L) PH was 6.2 (as there was a calcium deficiency so I raised it slightly) PH is now 5.8 (I read lower PH is better for Iron Intake

Yellow spots on lower fan leaves
Hi Growers! First grow here and I am concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg deficiency? N deficiency? Too less water (100ml every 3days)?

Lack of water or its something else.
Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄

Help with Symptoms
What kind of deficiency or excess is this? I couldn´t find anything that matched it. It was from a bottom leaf that wasn´t getting much light and was pretty close to the soil. TIA!

Yellow leaves
Hi there, I have a Skunk #1 Auto plant, about 7 weeks old, at the starting of the 7th week some leaves started to turn yellow. I read two options, that it is an N deficiency, the other option that it is normal as the buds absorb the N from the leaves. Any ideas?

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Yellow and purple leaves
I stopped feeding beginning of the week because I had yellow tops on one of my buds. I think it is causing yellow leaves. Does that sound correct? Also I am seeing sort of a purple colouring on some of the leaves. Is that okay?

Discolored Older Fan Leaf
I’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?
