NOsnicklefritz Maybe fan or heat stress?

RoMag First, I would throughly inspect the grow for insects. It does appear from looking at picture 3 of 3 you have some type of insect problem. When you expand the picture out, you can inspect the plant leaves. There are several spots on the leaves that show signs of larvae. They appear kind of off white oblong specs all grouped together. Also inspect the underside of the leaves for signs of insect. Right now I would try and identify the insect. Regardless, the control for for most pests or insects would be the same. I don’t know how you are attempting to grow with or without pesticides or all organic. Read up on how to control pest in your cannabis garden. Additionally, I would suggest raising your light source to between 30” to 36”. I hope this helps.

Jimbo Norman I would guess heat or light stress…possibly the fan too but in my experience fan stress looks more like a fucked up ph issue with drying tips rather than subtle curling. Can’t comment on whether or not that’s an infestation…but if it is you might look into Dr Zymes. I try to stay organic and had to use that last fall for an outdoor grow that had both spider mite and mold issues. It eradicated the spider mites but I had to keep punching the mold back every couple weeks until harvest - once the fungi sets in it’s very difficult to get rid of. I used Dr Zymes in the Canna Fogger 👌
