Looks like acid burn. Maybe a drop of nutrients hit the leaf?

Brown spots on older fan leaves
Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.

Thoughts, should I be concerned?
One of my plants is developing twisted and spotted leaves. Is it just to much nutrients or something more?

Did I drown my plant? Stress it? I gave a lot of water in a short duration of time, and now 7 days later she is looking terrible! Read my diary on week 17 for more info!

Hi, I'm at the end of flowering, I have about a week left before harvest and on one of my plants the leaves are turning a dark brown color. Do you know where this could come from?

Too soon for leaves to be turning brown and curling!
The auto widow circular leaves are curling at the tips and the tips are turning brown, and one of the pineapple kush auto circular leaves is not only brown at the tip but looks like about a third of it on the end is gone. See photos. What might be going on and what can I do?

Brown spots with slight yellowing
Hello gromies. I'm seeing some slight yellowing and brown spots on my fan leaves. I've been bottom feeding so maybe it's a lock out issue with calmag. I flushed with tap to get some run off. Any suggestions?

Only single leaf, still cal/mag?
Anyone knows what causes a single leaf to show rust patterns, almost like cal/mag deficiency. Whole plant looks healthy except for this one leaf, literally. DWC, and I use tap water

Why is my WW seedling browning?
I have a White Widow seedling that is showing brown spots. I am not sure if the LED light was too close, or if it is showing nutrient deficiencies/excesses. pH=5.8, PPM=160 (80ppm in well water).

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight
