I haven't had it, but my research says a resounding yes. Whats your plan of attack?

It's hard for me to see on my phone but I would get out a scope for a bug inspection too. Look at underside of the leaves

Bug free. What would indicate some type of critter? Hopefully not missing something.
Under 40x I can clearly see tricombs (clear) but also see very light webbing.
Plan of attack.
• early recognition
• drop overall humidity from 40-45% to 30-35%
• increase exhaust from 125 cfm to 250 cfm
• install additional 6" fan below canopy
• maintain min temp of 70'f preferrpreferably 74-76'f
• Lightly spray entire garden with 15% hydrogen peroxide to RO water.
I hopefully got it early enough and I'm fairly far in flower.
Even if I just plucked to prevent the girls would make the last couple weeks with the environment change (I hope).
The spray has worked well in the past, but that was 25 years ago.

Spider mites make very light webbing. You may have more going on than you think.

Thanks for the heads up.
I gave a very thorough examination this morning and definitely no critters. Thank goodness. I really don't need that too.
Treatment went extremely well. I believe I got it early enough. I will treat three .ore times just incase, but 95% of the spotting is gone and I removed about 10 leaves.
The low humidity is causing the plant to consume double the water.

Critters are just part of the mix. It's inevitable. THey aren't hard to control, you just have to put it in the schedule! Good on the improvement, CHeers! 
Light webbing is often the result of mites. Not always, but often.
What else would indicate some sort of insect? Sometimes the areas the insects are feeding can show spots.
Good luck.
