stop feeding nitrogen at this point or the lowest you can.,
what npk ratio are you feeding?

im not to sure the ratio those numbers get me lost
but i do give half the dose recomended they say to give 4ml of grow bloom and micro to 1ltr of water. the cal/mag im using says 1ml to 1ltr of water. and the monosilicic is harder only a few drops, 20drops = 1ml to 10ltrs of water.

thats all i feed them

do you have 3 weeks left? roughly?
thinking of a feeding mixture for you with what you got..

Could bea few things.. the burnt curled tips are typically light burn but there also looks like there could be a mite issue with the small white specks. flip those leaves over and see if you see small black dots. Also you dont need cal mag. The healthy part of the leaves are deep dark green ruling that out.. Im thinking light burn

When I am in a position such as you and I can't diagnose the problem, I just feed them a light casting tea and back the light off. The tea contains a flush of decent microbes and some light nutrients. And backing the light off takes stress off the plant while it figures its life out. A sprouted seed tea will give you a nice boost of aminos that your plant would have to otherwise manufacture.

Just some of the things I would do that late in flower.

PH Perfect is at full dose, you shouldn't add calmag on feed days with Advanced nutrients MGB, switch to thier new better version Sensi Grow/Bloom. They have powdered now, save some cash better formula etc..

How often is your feed schedule per week?

 

[jdog22]

not sure with coco, I am using promix bx, similar meaning its not amended, it's peat based. advanced ph mgb nutes are are only recommended twice a week with water in between and even then it's hot at a full dose and you see leaves burnt tip all throughout grow cycle. I would do a flush water only no cal mag. then very light nutes next, water then, 1200 ppm whatever the mix ratio is to get around that number till 2 weeks left to harvest water only, you shouldn't need calmag unless you are running r/o water. If so throw a calmag feed in, fresh water then nutes repeat. that's similar to how I have been successful using Advanced nutes PH perfect
