Looks like Mag deficiency.
One pic, you can see a claw, are a lot of leafs like this as well? Nitrogen might be high as well
Temps?
Thanks for getting back to me - temps are around 79-83 and humidity is 60-70%
I do have more plants with a slight claw
Always ph my water between 5.7-6.1 and unit is calibrated?
Curious...what nutrients are you using and what ec are you feeding @ ?
Your RH is fine considering VPD, imo
I was having similar issues until I read somebody's journal (imo is a coco master) on a different website. I raised my ph to 6.2 -6.3 and all cal-mag leaf issues disappeared.I’m using Floraflex V1 and V2 feeding between 1.3-1.5 ec water is 65-75 and I’m in coco ph probe is calibrated etc
I feed 1tsp per gallon of calimagic

How much magnesium are you feeding your ladies. I was chronically under feeding them.
V2 is only 2% magnesium
I hit them with a 1/2tsp of Epsom yesterday and fed them 2 grams per gallon omg Epsom salt with an ec of 1.1
They are looking better. I’ll update photos tomorrow
