Does this look like a deficiency or pest?

[Blimpsious]

Have a trio of ladies outside, 2 White Widow and a Purple Dream. Always PH my water and have consistently added 2.5ml of Cal-Mag plus to the mix. Noticed these spots on one lady a week or two ago and now I'm seeing them on all three. Figured it was something snacking on them so I went and bought a high quality Neem oil to dilute and use on the leaves but the problem seems to be accelerating. ANY help is appreciated.

Yikes!
First I thought mites, but never seen damage like that from mites so thrips?
Mites tend to bite in clusters near veins - I can't see a pattern there

not a deficiency... im thinking mites.. big healthy ones

Mine look like that when I have thrips. No matter as they are treated the same way.

I think maybe you have two different culprits here. You have the classic white specks that appear with mites, but also the big lacy holes, which is not typical of mites. As @Azimuth stated they are probably treated the same so I guess it isn't an important distinction, unless the thing that made the holes is not susceptible, so you will have to watch.

Look under the leaves with a loupe or magnifying glass, you should be able to see those little effers!

Ty. I found a video someone posted in there with a recipe to hopefully nuke these little pricks.

Best to identify the pest first. Those holes make me think of caterpillars, inchworms, and the like. Look for very small green caterpillars. Could be on the underside of leaves. Could be here and there. There may only be a few, in which case remove by hand or tweezers. Bt is a good organic treatment for such critters.
