Mites?

Ok so I searched a little on the net but I only seem to find other peoples pictures, if they got mites. I'm a first time grower, I got 9 of these plants (planted seed april 15th). Now they just finished their 3rd week into flowering.

Do they have mites or is this mainly thrips which I know I got loads of. I want to treat them against thrips but I heard it's bad if you already went to flowering... Another question..is the development of the buds seem terribly slow to have passed 3 weeks into flowering?? I have had heat problems since day one (something u might want to know).

Anyhow I see small white spots and mini black spots on the leaves. All sets of leaves at the bottom and if you go some nodes upward - are turning yellow and a little brown (like some nutrient burn which I dont use but I've seen pics of)

Sorry for the bad pictures, I only have my computer to take photos with.
600w hps, they are 4-5 feet in height. I should have 5 weeks left before harvest +- 3 days

You don't need magnification to see spider mites, but you do have to look very closely.

Spider mites are generally red during winter months and black during summer.

Do the little black specks move around upon disturbing?.

If so, mites are among you.

I've read some and they say u need at least a 30x magnifying glass...
I'm not sure about if the black spots are moving, I'll check it tomorrow when i'm at my friends house. How is the webbing noticed if you could describe to me a little more, thanks

Ok me & my friend checked this morning for the blackspots, even on leaves that have been removed because of the yellowing/browning. The black spots do not seem to move!!! Now if anyone could please answer how bad this is about spraying thrips: I switched to 12/12 the 7th this month and pre-sex was shown 5-7 days after that. I suppose im in my third week of flowering. I want to spray the whole plant with pyrex (contains pyrethrin). How bad could that be to the buds? First maybe I should wear gloves and touch alllll leaves to kill thrips, then afterwards I use the spray method bcs the thrips are also on the stem. What's best for the buds? Thanks & peace
