Help wanted...what is this?

[kannakid]

There are a few white spots on some of my leaves and I've been unable to find a definite answer. I was thinking maybe spider mites but from looking at some spider mite infested plants it didn't really look the same. Now I did have a few smaller leaves that were beginning to form some white powdery mildew but I quickly removed them and I haven't seen any more growth. Anybody else run into a similar problem?

Take pictures under natural light.

The vast majority of leaf problems originate from the underside, so make sure and inspect the bottom of your leaves.

Do you do any foliar applications?

The underside looks fine, nothing out of the ordinary. Here I hope these are better. (The second pic is of the underside)

As of now no I do not.

are you running a humidifier with tap water? I know when I do that I get calcium deposits all over the tent. I thought it was PM till I realized what was happening lol

It's possible it's a burn from spraying or dripped liquid on while too close to the light. I wouldn't be too worried about it.

Ahh, I was running a small humidifier for a little bit but I took it out recently, that's probably what caused it. Appreciate it!

yeah freaked me the fuck out also, but definitely keep an eye if you splash anything or apply anything on the leaves also. my leaf tips always get into my cup as im watering the plant, so I always have that also. freaked me the fuck out also til I realized that, too.
