idk what the yellowing is but you need some magnesium. It could be a PH problem, 5.5-6.5 is the optimal range for cannabis.

My first time growing and my clone has started to get these brown dots everywhere. Now some of the leaves are dying and it’s getting worse. Online it says it could be mildew or a calcium deficiency.

nitrogen deficiency
Hi guys, my plant has a nitrogen deficiency, but I dont know how to fix it. The ph value is correct and I already gave her a lot of CalMag, but things doesnt get better. She already lost 4 leaves and the plant in general looks a lot brighter.

Yellowing leaves after first Mainline top. Light stress?
Just checking in here, I am pretty sure this is light stress. it was at 18" (specs say 18-24" during veg) and she was likely pretty stressed after having her top cut off!!! I have raised light to 23". Am I on the right track here?

Is this overfeeding or another more complex problem
This is my first Automatic plant culture. I've made some novice mistakes, such as topping the plants. They start flowering about 2 weeks ago, but the leaves are turning yellow with some brown spots. I feed with an old Nutrient I had here. Can that be the problem?

Harvest close but yellowing fast!
Looking at my last pictures, I see the Purple yellowing very fast but, on the trichs pictures, you can't see any amber on her yet. I was planning a few more days before harvest that purple, but could that damage the buds? If it so I would harvest. What would you do? Many thanks!

Underwatering Issue or something else?
I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering? I’ve been pHing between 6.2-6.4
