It looks like calcium deficiency. I'm not familiar with your brand of nutes, but wonder if you've developed a lockout.

Yeah. Looks like what I've had when there were calcium issues.

I'm not on top of what all the BioBizz stuff does, but whatever water you're using and how hard it is (and what that hardness is) may also play a role.

I'm using the Bio bizz range including there soil, water is very hard at 8.4 so I use 75% RO with 25% Tap, PH 6.5 after adding PH down.
The RO, Tap water mix still creeps from PH 6.5 back to 7.2 over 24Hrs.

did a cal mag foliage spread yesterday and not noticed any improvement.

I moved from using my well water to filtering it or using my dehumidifier condensate...I was just having trouble with calcium and magnesium issues, and that was with my water in the .45-.65EC range. And while everyone assumes that the hardness was calcium based, I was still having deficiencies, and I couldn't seem to get out from under that, even when using Ca/Mg, etc. So most likely a case where there was a lock-out based on another nutrient.

I will give straight RO water a go to see if it improves, if I can’t see any mites.

Will I see mites moving ?
Yes but you have to look carefully-
You may see some tiny eggs also
I went on vacation for about 2 weeks and upon my return i had leaf spotting on 1 plant.
I thought it was a nutrient issue- I switched to 12/12 when I got back and a couple weeks later- just into decent white pistols- I looked under a loupe to find the plant was infested with spider mites. It was a beautiful plant however I decided to immediately dispose it and treated the remaining plants with Green Clean- safe natural ingredients that can be applied nearly to harvest- i was not close to being finished so I treated a couple times and mist with water a few times in between.
Fuckers will suck the life out of the plant.

I hope you don’t have any- but a quick look earlier and I probably could have saved the plant. Treating the underside of the leaves is difficult so I decided to trash it before the rest of the crop was contaminated.
So far the recovery has gone well.

I’m praying it’s not mites, I have a Runtz muffin, 4 weeks in Veg and 2 seedlings all looking good in the same tent
