Spots and more spots

I have a small girl in veg and she is now covered with these spots. Well, I trimmed them all off, but she was covered in these. I have been reading everything from low nitrogen, low calcium. My RH has been fluctuating because the rain in the area, so I got a DeHumid unit for the room at it stays at about 50% now... also read about a fungal thing that’s specific to cannibus...was only this plant at first but now few other leaves on other plants have small spots...this plant is a “bag seed” the others are from a trusted seed bank. Could bad genetics be a problem? I got nervous that it was infectious and trimmed all leaves with spots.

Looks like you've got heat stress for one.

The white spots almost look like you've dripped feed on the leaves with the pic you've shown, but white spots on the top of leaves could also mean pest infection. Look at the bottom of the leaves with a loupe or magnifying glass to see if you've got bugs sucking the juices out of the plant.

I have checked and checked for bugs but have seen none...I sprayed fox farms Don’t bug me on the leaves day or so before the spots..lights were on. Maybe that had something to do with the spots? Did I burn the leaves with the magnification of the liquid?

It's very possible that the spray you used caused slight burning of the leaves, yes. That said, I've never used that product before, so I'm unsure if that would cause it or not.

Just keep your eyes open for any sign of infestation, particularly the webs of spider mites.

Aside from that, I personally wouldn't spray my plants with anything proactively, if there are no signs of trouble.
