Deficiency identification

Hello all,
I'm struggling to identify the issue with my plants. The issue is predominately on 1 (i'm growing 2). Overall they are quite green and healthy from what I can tell.
Here are the basic details:
-green crack
-5ga fabric bag, outdoor, potting soil
-GP floranova grow every 3 or 4 waterings
-watering them daily but just until a bit of water starts to trickle out the bottom. They're usually ready for a watering the next morning (its been 30 degrees and sunny here recently)
My first thought was calcium deficiency but the affected leaves are lower on the plant and mostly under the canopy. Any suggestions are appreciated.

Cheers!

Looks like the beginning of a little russet mite damage & Magnesium Def. I would spray with neem & garlic water along with a little Epsom salts. If that's the problem of course. Any pics of the leaf undersides?

Here are the undersides. Neem & garlic for the mites and epsom salts for the mag def?

For future reference...

It's looking like that should do the trick. Remove any potential host plants and give the area a good thorough clean. Apply the foliar every other night till you have it under control and then maybe 1-2 / week till flower. Make sure to spray the soil as well as they can lay their eggs there. Worked for me in the past.

Thanks. I only have 2 plants on a balcony so not sure where they would have come from.

You just add neem oil and and grounded up garlic in a homemade mix?

I've had similar problems on balconies. They can come from anywhere really.
Neem Oil with finely grated garlic and R/O water (or ph'd 6.5-7 dechlorinated water) should do. Begins to smell like funky garlic cheese strains after it ferments a little. I kind of like it although it's a bit offensive.

Thanks. I was actually thinking of getting a similar one but for examining the buds to gauge when ready to harvest.
