Just started week 5 of flower and starting to see this on a few plants down one end. Seems to be progressing to more leaves. Any help is greatly appreciated
Ah thanks mate, I’ve got a small mite problem I’m trying to combat with potassium soap and some leaves are just small spots. The leaves that are like this don’t have the little spots like the others. Could it be different types of mites you think?
Any other ideas guys. It’s gwtting worse quite quickly so don’t think it’s a mite issue as there’s really not many of them. Leaves are starting to curl up too like they’re drying out
How about some clues. What water are you using. Tap? If so, what's the ppm? When leaves are drying and dieing, I tend to think there's a Ca issue...as in too much. See any brown spots?

Whats the temp down that end? To me I think its Cal deficiency, which effects the plants transpiration. That then causes leaves to be dry from temps or lack of proper airflow. Check your feedwater PH after adding nutes and add some Cal/Mag
That’s literally the same type of deficiencies I get when I’m not using enough cal/mag and Epsom salts. Now my plants are hogs for cal and mag but worth a shot anyways
I’ll get drying leaves at higher rates, like 6 oz per gallon.
I read 6 oz per gal as a recommended rate somewhere, didn’t start being an issue until the third app. Went away after stopping soap app.
I find 1-2 oz per gallon ineffective, but it is the most common recommended rate I see
