Plant needs more potassium. A P/K booster will help, or increase the amount if you are already using some.

Most likely turning yellow because it's getting to the end of its life cycle.... I don't see anything to worry about except the length of time you're going to be in trim jail in the near future! Good luck!

So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore? Thanks for answering!

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?

1st grow yellow leaves and brown spots
Last two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(

Super soil needs activation?
There are plenty of nutrients in my supers soil. However I heard that the problem might be that the soil isnt "activated" is that logical? Thus need to add organic ferts? I am trying this, but I'm sure the super soil has months of nutes in it!

Is my plant showing signs of Nitrogen deficiency?
Autoflower, day 40. Most leaves are in a yellowish-green tone or even completely yellow. I was mistakenly watering it with tap water, but when I noticed the yellowing, 1 week ago, I started watering with mineral water at pH 6.49.

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.
Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

Yellowing of leaves during flower
What is causing yellowing of the bottom/backside fan leaves during week 5 of flower? Should I worry about it spreading? Increased bloom nutrients to 3ml/l recently but could have started when feeding 2ml/l. Or is this just leaves yellowing as a part of flowering?
