I have been vegging some widows for 2 weeks. They are young, but last week I noticed a white powder, UNLIKE any white powder Ive seen reported on this website. A lot of pics I see here are blotches of white, with leaf degradation. My spots are so small they cannot be seen with the naked eye, I need a magnifying glass. Also, the spots are unusual... they look like tiny tiny tiny salt crystals evenly distributed on the leaves, pretty spaced apart. What's unusual is that although Ive seen them for the past week, the white dots have not changed in numbers or size. They are the same. Also, the plants themselves are still healthy, growing, no degradation of any part of the plant yet. I'm baffled, I know theyre not bugs becaues I've inspected all the plants top to bottom. All I see are occasional black specs, which don't resemble bugs, do not move when disturbed, etc. I figured it may be fungus, but the plants seem OK and the spots have not physically changed over the course of the week, which is surprising because I thought mold grows fast (I heard up to 48hours for reproduction). So what is it???? Is it possible at all that these spots are natural and/or harmless?? If not, will neem oil fungicide do the trick? Will it be a constant maintenance issue from now on, or will fungicide get rid of it for good? I know bugs are a whole other issue in that respect.....
