Pale/White spots and specks on leaves?

So I have had my room dialed in for a while now and this is the first time I'm coming across something like this or any problem for that matter... I went on vacation for a week and had a friend look over them, I came back and the leaves especially the bottom fan leaves seem to have white spots all over them and one or two of the very bottom most leaves seem to have turned a bit yellow on the fringes (looks like it was was burned almost).

Im running a 1000 watt at 50% and is about 2 feet above the plants more or less
RH - 45%
Temp - 81 day/73 night

Nutes
Growmore seaweed extract
GH micro/bloom
Mad Farmer NUTS

PPM is at 325
PH is at 6.0-6.2

Here are some pics.

Can anyone tell me whats wrong with me Ladies?

I checked the underside of leaves very closely for spider mites however my microscope got busted and my new one I ordered hasnt arrived yet

Flip the leaves over look underneath for mites man get a scope or magnifier and look

Calcium deficiency, early sign.

Your ppm seems low. Try doubling it from 325 to 600 - 700.

Ph is too high imo. Set it at 5.7 and let drift up to 5.9. 5.8 is the sweet spot for most strains in hydro, a few like 5.6 more than 5.8...

SO after looking more closely it turned out to be spider mites. They really are the size of a pin head and hard to see, its even harder to see them move without a microscope. They look like brownish specks. I also saw white balls, im guessing these were eggs. As for the black dots.... I can only assume these were the fecal droppings from dining on my ladies... For anyone else dealing with the same problem and thinking it might be spider mites here what I did....

I bought habanero peppers, diced 2-3 of em, and simmered on low heat for about 15 mins in half a liter of distilled water. Do not let the water boil.

I soaked paper towels in diluted isopropyl alcohol and ripped them in the middle half way down. I then covered the top of the net pots with the soaked paper towels around the stem. This was in case that if any mites dropped from the leaves they would land on the alcohol soaked paper towels and instantly be killed.

Let the pepper spray cool to room temperature, strain, and fill a fine mister spray bottle with your pepper solution and spray your plants until they are dripping wet from top to bottom making sure you cover the undersides of the leaves, even the smaller new growth close to the stem, get in there.

Just to be sure I took a spray bottle filled with isopropyl alcohol and sprayed/wiped down the entire tent. You can never be too careful when your fighting something that you cant see...

Repeat these steps and spray down your plants 2-3 days making sure that they you get em all especially the eggs...

Your habanero pepper solution will keep in a refrigerator indefinitely but should probably be used within a week

TIPS

WEAR A BANDANA OR MASK. I learned the hard way... As you spray down the plants you will inhale the pepper spray and it does burn and make you cough... The fumes from the alcohol burn too...

Turn off all fans blowing in the room unless you want a face full of pepper spray...

You can tell if your pepper spray solution is done by putting your face close to it.. if your eyes, nose, throat, or skin burns.... its done.

Hope this helps anyone that finds themself in a similar situation
