A few of my peppers have that on the underside of the leaves but I dont see anything move. Theres nothing moving and all plants look perfectly healthy.No cobwebs either,Its like tiny tiny crystalls. I have the vent to my room from the growbox on lowest permanently and once a day let it vent all the air on max

In short: Edema or “VPD”.
It’s explained in this video by Chilichump:

Edema.
It happens when plants can’t evaporate water fast enough. It practically always happens with indoor plants before you move them outside, and it’s not catastrophic. You can alleviate it by:
– bottom watering
– regular watering and less at a time
– good ventilation (for example using a ventilator on a timer, for something like 30 mins every two hours during the day
Looks like edema. Increase your airflow/reduce humidity
That is called edema. The humidity in your tent is too high. I’ve had it happen before and once the plants were moved out to the field it cleared up and the plants seemed to recover just fine.
this is edema. it can come from a number of issues but often improper ventilation, irregular watering, or fertilizer can cause it to happen. peppers are a bit prone to it in my experience but with some adjustments they tend to recover well
