Hiya PC, long time…… sorry to see your dealing with lockout issues.
1st thing i'd do is ditch the Tap altogether.
That way you know Exactly what your giving your plants.
What nutes are you using?
What kind of Calmag?
How old is the Calmag/ nutes?
What ppm and I would just use RO / cal mag on the gsc. It's super sensitive I noticed
600 is high. I recommend 50, 100 max for a starting point.
I run calimagic at 4-5 ml/g till week 5. I wanna say lockout based on the acute severity that late in flower.
I forget which element is antagonistic to Calcium? Maybe that's the issue? Not to mention Ca is immobile.
Is it ur only cookie plant or is this a specific pheno of a group ?
Looks like a severe Ca- to me, brother. I'd be using a product that's Ca only, not a combination Cal-Mag product. You can foliar the Ca if you're concerned about bumping up EC too high, but honestly, they look to be more than halfway done with, what, maybe a month more to go? IMO it's a bit too late to try to play catch-up to the Ca train.BTW I was thinking more Calcium was needed or its getting locked out?
