Calmag deficiency?or light burn?

[swantip]

Help! is this the start of calmag deficiency?or is it a light burn?i used to spray the bottom of the plants and there were some droplets on the leaves with the lights on.. 2 different plants slightly different spots

well after further research i believe this might be wind burn.This might also explain the clawing on her leaves too.Readjusted my fan, we'll see

That would be a lot of wind - you've got dead leaf material in the middle of a leaf surface.

I see white spots in some of the healthy leaves. Check the underside of your leaves and you have to go to 60x - these little assholes are really small. Check the interwebz for things to look at. I had a thrip infestation last summer and it was brutal. Little green bastards…

Don't want to sound alarmist but I'm a new grower and it's something I just never even thought about until it kicked my ass.
