Any idea on what this is. Nutes have been cut and just ph'd water being fed. Had a little mishap with pH on one feed where I didn't pH the water.

Maybe phosphate? Let someone else come in, but, what are you giving them?
 
Any other spots on the plant? Phosphate starts at the bottom I guess. Looks similar (to me).

What's the medium?
 
Cococoir :).
surrounding that cola yes but not that I could see anywhere else. Small very faint spots on one or two other leafs.
 
Ok I am not sure about it really. Hopefully someone with more experience will chime in.

Your leaves edges don't look too good either. What's the humidity been like? Co2 (fresh air)?

And, I think you should be feeding in Coco. Have you been giving any nutes? How far along in flower or grow are you?
 
Day 70. Been healthy apart from Cal deficiency early on. Humidity sits between 55% light off and 40% when light on. Trichomes are still transparent but figured I could give this one a good "flush". Fresh air is taken from room adjacent and heat exhausted thru wall to outside.
Heats always been an issue and always will until I get an AC unit or cooling fan. "Small space"

I wouldn’t feed just plain water in coco. Try a diluted nute mix of about 25% strength if you’re trying to flush. Just curious as to why you have feeding straight water anyway?


Easy smoking! [emoji869]
