I’m not really sure what this is

Appears to maybe be a Ca deficiency not sure. It’s not on new growth more so around bottom and middle. Even leaves in shade show this.
This is a rdwc plant. Feed is 200 ppm cal mag 800 food tap water 170. Ph has been good through out the grow at 5.6-6.3 When I change the water it goes a little high like 6.3 takes a day or two to get it to 5.7 then it stays.
Plant is 30 days into flower and this just started showing up.

Grab a scope and look at the underside of the leaves closely! Shake the plants as well a bit and see if anything flies off of them.
 
I do have a thrip here and there,though there marks are different I thought?
Ive scoped them and i see brown circles
thanks
ill get a pic up
 
It's not Ca then. Could be bugs like Blitz is hinting toward, but doesn't look so much like that either.

Can you get a natural light pic?

There are some white specs on the leaves that aren't part of the leaves themselves... Just zoomed in.
 
Here’s a pic.
I see the white specs also 3 rd monkey not sure what that is.

Can you explain your feed a little better? Tap is 170, what's the rest? 1200ppm total?

just hydro food. 3 part. 1-2 for veg 2-3 for flower. I don’t get this problem in veg. Part 1 grow is 1-2-5 part 2 is 2-0-0. Part 3 is bloom 0-4-4 so veg is part one and two. Bloom is part 2 and 3
Tap water is hard 170 ppm .7 scale suppose to be Ca and mg in it but plants yellow in veg without adding calmag.
I’m mixing to about 800 ppm in food
First pic is Pand K part 3 second is part 1 part 2 is N 2% and Ca 2%
I’m trying a week of no calmag to see if any change

Something maybe missing in my flower nutes?IDK.

They're feeding and drinking good and it doesn't look bad in the pic, so don't sweat it too much.

I think you did the right thing withholding calmag for a bit. Should be quick feedback.

How was the ph swing in veg? If it stayed to the higher side, might be just a tad low for that plant.

ph in veg... was probably a point or two higher then now.small system in veg 45 litres flower 100 litres.Water would drop a lot in veg ,top ups were 15 lires so a third.ph would be 6.3 ish for a day or two till i got it down to 5.8.flower is easier to keep below 6.

so ya maybe ill up it a bit after this week,thanks
