Noticed a couple of weak leaves and took them off a Northern Lights Auto, and looked at the underside with a Digital Microscope.
I was concerned they might be mites, but they don't move or seem alive. Wonder if they might be 'sap' from a damaged spot.
Has anyone else seen this?
Last pic is one I knocked off the leaf.

It's probably some kind of egg sac. Don't wait to see what pops out.

I don't remember ever seeing this on mine so I just got done reading a bit about it. Very interesting phenomenon.

I stumped... plant gall? Guttation? Egg embryo? I uploaded to an AI. It thinks that is a normal trichome... a bulbous one instead of stalked. The bulbous ones on buds look like dew drops. That one looks milky/opaque. Hmmm maybe it is?
