Deficiency, pest, or fungus? Or worse?

White spots on some of the leaves, I think it's slowly spreading.
The bigger plants on the right are affected. I don't *see* any bugs but they may be there.IMGP4547.JPG IMGP4547.JPG IMGP4548.JPG IMGP4549.JPG IMGP4550.JPG IMGP4554.JPG IMGP4555.JPG IMGP4556.JPG

A good miticide should do the trick. Douse them..and check them daily, if you're getting close to flower especially

If you can put them outside for a week or so ive noticed natural predators usually consume them fairly quick, worked for me anyway. If you cant put them out, well your at the mercy of chemical alternatives (Azamax) or something similar, or you can try predator mites although i have not heard of good results they cant keep up with the rapid reproduction. That being said if you put them outside you run the risk of bringing new problems back inside. Im growing inside and out this year and both crops have been just as stressful. Think spider mites suck? Wait until you deal with four lined bugs, Japanese beetles, ground hogs, cops, deer, and rippers. Good luck man!

it could be bugs or you are spraying them with water/feed on the leaves and your light is burning holes in the leaves. either way get it fixed before your plant is no more. What type of light are you using? HID? Do you have a 30-60x scope to check for bugs?

Yes, I do have a scope, the $10 one from radio shack. I can't find any bugs at all. Or egg masses. I even shook the leaves over paper to knock anything loose. Nothing.
Running a 600w air cooled. I have misted the leaves before (R/O), but I don't think it's that since lower leaves are affected as much, or more than upper leaves.

MG organic potting soil with composted manure, perlite, and granulated lime is the medium. Go box nutes, heavy schedule. R/O water mostly. Used rain water the last couple of times. Adding GO box "cal-mag" as well. Jamaican Dream, about a month old.

That scope should be enough to see bugs, right?

Also, they were in/out from seed up until about a week ago, right next to the tomatoes.
Outside during the day, in the tent at night to finish the on cycle. Been at 19/5 for about 10 days. (that works better for me than 18/6 schedule-wise)

I know that's risky for all sorts of reasons but I deemed that risk acceptable, and I'm not yet convinced that's what started it.

Thanks for the help, fellow growers. What can I do to help you with a better diagnosis?
Unfortunately, I can't take a leaf to the neighborhood nursery.

since you are moving them in and out it could be white moths and many other things. I would spray them to be safe then when you flower them you cant use any chemical just pepper spray then, I had the same thing form water burning holes in mine down 2/3rds of the plant and it was from misting them. I use sevin for all outdoor plants. I never spray the mj plants when it start flowering except with my homemade pepper spray
