Are plant's infected with pest's Not that I can tell, except for the odd little black fly that gets caught on sticky fly paper in the tent every once in a while.

So this problem just popped up on 1 of my C-plus, while every other plant in the tent looks fine. I am having a hell of a time figuring out what is wrong, since my ph/temps/rh seem to be fine. The spots seem to only be on the fan leaves at the moment. Any ideas?

check for bugs seismic ....take a scope and chekc under the damaged leaves it does look similar like some bug damage or maybe something you spilled on the leaves ?

Thanks core, I checked under the leaves, and on top, and all I saw were a few of the things circled in red in this picture:

Are these spidermite eggs?

 

[whodi]

I took the picture from the infirmary, as it is not a picture of mine. I wasn't sure if it was mites or not, since i found those round things mostly on top, and I saw no signs of any crawling creatures.. But just in case I have introduced some ladybugs into the tent, and will continue to maintain there population levels in there, as they die off. I also have some safer insecticidal soap, but I was unsure if it was ok to spray the plant at its current state in flowering. They are currently 26 days in and look like:

I was checking with the scope again, and it seems like what I was seeing may be just really small trichs, because there no where near as large as the dots in the picture. Hopefully its not an infestation.
