almost looks like a pest issue... possibly russet mites.. is this outdoors? Indoors? Do you have any IPM programs in place yet?

Should I trim yellow fan leaves?
would anyone bother trimming off the yellow fan leaves or just leave them? I have no issues with space or airflow - plus I kinda like the colours they have right now as they are getting near harvest time

Yellow/brown marks
My plants are becoming more yellow and now also showing some brown/yellow marks. I'm afraid it’s because I may have splashed some water containing a little bit of CalMag on them one time, not knowing better. Might that be the issue here? And most importantly, what should I do?

The leaves are yellowing, some are turning purple, maybe it's normal or maybe not, I don't know. If anyone could give me some suggestions. I decreased the light intensity to 75% because unfortunately I can't raise the lighthouse.

Why are my leaves yellowing. 6.5 ph maintained. Feeding fox farms tiger bloom and big bloom. Thinking it may have been from a late watering combined with the humidifier running out? Any help is appreciated

Yellow edges to leaves
Hello fellow growers. I have noticed some yellow edges to a handful of her leaves. pH droped a bit today down to 5.6 but has been stable at about 6.4 previously. Photos from the last few days show this problem has been creeping for a couple of days. Any ideas?

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?
