Hi Rider,

I appreciate the compliment. I'll do my best and hope that someone with MJ outdoor experience in HI will jump in (Weezard - where are you?).

First, I really can't tell anything much from your pictures. The close ups of the white spots are too blurry.

You mentioned small grey bugs? Are they still there? Without knowing what they are, or seeing them actually doing damage, you don't know that they actually did anything. The presence of a bug on an outside plant is not cause for panic unless you see damage from them. The odd small chomp is to be expected on an outside plant, usually no harm done.

Look closely at the undersides of your leaves, specifically on the new growth. Look for any webbing, specks, dirt, etc. If you see anything suspicious, try to get a magnifier or loupe to get a close look. Generally, insects present first in these area.

I understand your use of tobacco spray, but I would be really careful with that. Nicotine is a strong poison and some plants don't take to it well (not sure about MJ). Generally, just an insecticidal soap spray, without nicotine, will work on the average plant muncher. Be careful of the time you spray as spraying in strong sun can cause burning and leaf spotting. All that said, sometimes just a brisk shower with the hose and plain water will keep bugs at bay.

Do your plants stay in the same location or do you move them around? How long have these plants been blooming and when do you anticipate harvest?

All in all Rider, they look pretty good to me. Maybe some leaf burn from spray, a bit of overnuting, or even sunburn? I can't really tell from pics.

Maybe one of the "big guns" will look in. In the meantime, good luck.
