If this were indoor I would be checking ph of what goes in. I'm not sure how that translates to outdoor.

Leaves curling up a bit and dry on edges
Any idea what is causing the leaves to curl a bit on the edges? They are sour diesel growing in coco and perlite with a recirculating drip system, hlg 600R light about 36 in above and about 60%. Ph is 6, gh flora series 3 part nutes With cal-mag as well. I have a small fan that runs 24/7.

I was gonna write it up again specifically for your situation but it's better for me just to link you to this other thread. Is it possible your soil is over alkalized with too much lime, dolomite, rock dust, beef bone meal or some other alkaline input?

It is just plain ProMix HP. Didn’t add anything to it. Using Remo Micro, Grow, kelp, CaliMag, and Terpinator. 6ml of each in 1 gallon (4litres) of water. Use this for each feeding. 1 gallon per plant.

Not broad mites.
OP I think it could be a true boron deficiency per your description of setup, instead of a lockout due to other conditions. Pro mix is essentially a sterile soil-less medium. Just the peat, coco and perlite. Idk for certain but a lot of micro nutes don't contain boron, I would try to aquire a micro solution that states that it contains boron. This one is proprietary, ie they don't say what's in it. There should be a tiny amount in the kelp tho...
Some people would shy away from this since they are familiar with it as a cleaner and fire retardant, but borax can be top dressed, but the rate is like 1tbsp/50 soil gallons. So microscopic for smaller pots.
Also, could be exacerbated by a lack of biology in the soil? Top dress with worm castings, make a good tea with some molassis, compost and imo?

Will pick up some EWC today. BUT should I wait and apply when the soil dries up and I’m ready to do the next water/feed? And for the next water should i just go straight water?

Looks kinda like russet mite damage.

Overwatering can contribute or make things worse so you're right, I would wait until they want the water. See if the grow store has anything to say about boron in any micro products. I think the plants look like they're getting the right amount of nitrogen so I wouldn't say you necessarily need to cut back on food. I usually try changes in product when I'm having issues, consider a small bottle of alternate grow formula just to check that variable. Check that your cal mag application rate is not too high, I don't know that product. Excesses are often the cause of lockout. It's definitely a puzzle to me though, I have only seen this in conjunction with alkaline soils.

I would run straight water in the ones that are acting up as it looks like a little nute burn/toxic salts buildup starting to me. Before you water I would have some mix ready then lift those girls out of the pots and backfill the bottoms to get the pots filled up to the brim unless you plan on doing a lot of bulky top dressing that will fill up that space. I fill right to the top as it settles down an inch or two in big pots after the first full watering.
I use Promix HP with either AN or REMO nutes and have for ages. If they are going thru a lot of water I'd cut feed in half and feed every watering. They seem to like that better than twice as much half as often.

I doubt it's low boron as REMO has some in all 3 of it's base nutes. 20 Mule Team borax can be used for a supplement. Sprinkle a tsp on top and work it in a bit then water as usual. Or get some boric acid from the drug store and a tsp in 10gal is lots. Add to the water before adjusting pH as it will act like weak pH Down. It's a very rare deficiency.
Looking at the chart I think my damn kush might need a dash of boron as it keeps dropping yellow leaves but is still bushy as hell.

Pretty sure you have "black death" disease as described here https://www.icmag.com/forum/marijuana-growing/cannabis-infirmary/323206-help-identify-black-death-in-hawaii
and here
The chewed up looking new growth and purple tinges are tell tale signs of it...

I think it might be genetics. The 2 plants doing this are the same ones my Neighbor has and they are doing the exact same think. My other 2 are doing amazing! I dunno. I’m going to let them dry up really good then add a top dressing of EWC, and just water for the first couple of days. Less water, more frequent. See how that goes. Will post pics.

If you want to know for sure, for your own sanity, if you've got phytoplasmids or beet curly top or something, the only way forward is testing. I got my plants, photographed in previous posts, run for the gambit - thirty some pathogens - and was negative across the board.
On the genetics issue, I had several strains in the same dirt as the sick plants completely asymptomatic. I believe that the plants of the same strain tend towards the same needs and sensitivities.
My objection to that illustration of boron deficiency is the lack of detail concerning the kind of leaf deformation at the new growth tips... If you do an internet search you just get the same endless litany of nute and light and spray burn misidentified as a pathogen... Plus a few random photos of Russet that are tagged "hplvd" lol... the internet is a messy place.

If thats the case the plant is experiencing a radical hormonal shift and any signs of deficiency or over abundance of any nutrient has to be ignored because cannabis leaves behave extremely strangely in revegged plants.
However the growth looks like nitrogen toxicity probably a little too heavy on the nutes, too early…
