@Oscar Quintero What time of the light cycle were you treating for the spider mites, and what were you using?
What is the pH and PPM of the soil runoff? Are those the only leaves impacted or is the damage getting worse?
I’m On my way To the local hydroponics shop rn going to look for a meter for the ph and ppm but last week when I checked run off it was at 65 ph and other leaves are starting to be impacted all around
