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".

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?

Week Three slight leaf discoloration
In week three I'm seeing some slight discoloration. Not sure if it is something I should be concerned with. Using COCO, Worm Castings, ReCharge. Watering daily to keep the amendements active. Maybe I'm watering too much? Love to hear your thoughts. Thank you and happy growing.

The lower leaves of some plants are yellow, then die. I'm very light with nutrients, there is no bugs into the grow room, what can it be ? pH between 6 and 7, lower it with few drops of lemon juice but bought a 3aciddown bottle. And are the buds supposed to be that big already ?

Over the past 3 days my 2nd plant lower leaves started to yellow. Both are fed the same amount and the same rates. I noticed the one that is yellowing the leaves are upwards and that is a good sign, but the lower leaves are yellowing too fast. I am unsure what could cause this.

Yellowing copper leaves late flower
Harvest is coming up soon and I have noticed some of my leaves mostly the bottom but some on top also have started to turn yellow with brown/copper spots. I believe it is cal mag deficiency, will this mess with my yield or quality of the bud?
