Brown stains on leaves edges

blasterw32started grow question 6y ago

The top leaves on my GG#4 started to get brown on the edges. Initially I thought it was light burn, but the stains kept progressing after I readjusted the light distance. Is it a nut burn?

I don't think they're burned. Leaves burned by light behave differently. They twist and look dry. Your leaves look good, try to raise the PH a little to 6.5 if you are watering with a smaller value, or check the EC and play with the dosage of nutrients.

How's the quality?How would you rate the quality of these plants? The dark brown leaves have me self conscious of the roots situation. DIY supersoil mix recipe here: https://pastebin.com/pbxMZysq I've added more dolomite & guano as topdressing and fed liquid calmag and potassium during flowering.

I added a couple pics of what looks like rust spots on the leaves of only the tall plant in 7 gallon. I’ve given these two plants the exact same feeding so not sure what is causing it.
