m0useanswered grow question 3 years ago If you growing in Coco, perlite, worm castings treat it like hydro with liquid nutrients.
Your EC is way to high. Your leaves are dying out because of that.
calmg will use up half of your EC allowance when making feed.
May also want to adjust your PH as well. 5.8-5.9 for veg 6.2-6.3 for flower.
You should only run 24/0 if you have everything locked in and no issues,
I'd drop that down to 18/6 or 20/4, like others have posted, things need rest and should only do 24/0 for a short period of time.
Maybe give it a flush with clean ph'd water and go from there before anything else happens.
Best Of Luck!
