Meg has moved out but she's having troubles

Ok would like to say thank you to everyone here at rollitup for getting me this far but your girl has ran into a problem maybe two I'm new I really don't know which is why I need y'all.Ok first off I'm using Botainacare Cocogro mixed with perlite the plants are jillybean clones just passed 2 week stretch going on first week of flower i'm using Ionic bloom 2tsp.,Cal-Mag Plus 2tsp.,Liquid Koolbloom 1/2 tsp.,Ionic Grow 1 tsp.,and Liquid Karma 2 tsp. per gallon ph'ed to 6.0 temps at 80f humidity at 40% what in the world am I doing wrong I'm so frustrated this is really starting to effect my mood I know that's crazy but these are my babies.

i had a similar problem, mine turned out to be k and mg overdose (nute burn in a way) so i stuck to plain water for a couple of weeks and i nursed her back to health.

no more food. straight water for the rest of the week. that leaf is not going to turn back to green so pay attention to the top of the plant to see any result. if they start to grow more leaf then ur back on track .

Just straight water I thought I couldn't feed coco without some nutes what if I flush with a lower nute solution and I thank y'all for the replys.

is it only on the mature leaves ?????

Yes it's just the mature leaves from the bottom up.

that sounds like a lot of nutes to be using at 1 time, i'm on my first coco run and don't like it compared to soil i would do as the guys above said and give them water for a week, i'd also ease up on the nutes when you do start feeding them again maybe just a small amount of grow and flower and then increase the flower also i feed and then water twice in a row after and then move up to alternating feed and water if it's even needed? i only got a couple of wks left before chopping them and i can't see me adding any extra feeds into the schedule. i fell lucky and burnt my plants slightly early on in veg and learned early that less is definitely more in coco

well if its in the older leaves it means a "mobile nutrient" the plant is taking its nutrient sinks from the older leaves and bring them to the new growth off the top of my head i cant rember all the moblie nuits but i rember NPK are all moblie id suggest fertizling with just the ionic bloom reicpe and ditch the other stuff cal mag on tea spoon per gallon never any more And than follar feed with ionic grow and sm90 or a few drops of dawn dish soap as an emuispher any more question fell free to email my ass or what ever they call it on roll it up
