Little help with what happened.

I have had a grow growing and things were looking great until today.
I had seen a few white spots over time on the leaves but just a few, today I opened the tent and tons more.
2 days ago I watered and it was my second feeding of Dr. Earth Flower Girl.
I had started with 1/2 strength 1st watering, then after seeing no negative signs I moved forward with full strength last 2 watering.
I have been logging progress on this my original thread :https://www.rollitup.org/t/old-dude-newbie-looking-for-knowledge-my-first-post.909671/page-5

Last wed. was my last post there with a pic and the leaves did not look like this.
Here are pics of what they look like today.
I got my magnifier and looked all over for bugs, under leaves as well.
Did not see a one.
Nutrient burn?
Thirps?(think I would see them)
Mites?(think I would see them)
A deficiency?

Thanks for any help.

Sorry I didn't post this in plant problem section, If the mod could move it? Thanks

Did you foliar feed the plant ? or just water it into soil

Mixed to water I put on soil. No foliage feeding to date.

Looks a little like thrip damage. Look carefully for bugs, especially on the undersides of leaves. If you spot any, drench with spinosad.

That is what is trippin me out i got out my mag visor and another glass and took bunch pics on the underside so I could inspect -figured I would see something. I didn't. But I am going to look again dog gone it

Would it hurt to treat it for thrips whether I see them or not?

I think I would go ahead and do the spinosad just for good measure. I use it on my clones as a preventative since my last thrip outbreak. Can't say it works, but so far for me, no thrips.

I've been told neem oil is good for pests.

Neem oil is good but not in flower. It has a very strong odor.

Didn't know it was smelly.

Ok thanks for the replies, I was able to magnify further and saw thrips. Tried for a pic but they seem to run from the light.
So should I use spinosad since I am in flowering?
Any other things I should consider, use or deal with?
