From the pics it looks like you have a bit of Mag deficiency. Add a bit of Cal/Mag or 1 gram/gal of epson salts.
Good luck on your grow, just watch your plants.

You probably need to water everyday 2x a day with a pH of 5.5-5.8 and that young a ppm of around 350 is how I do it and they love it. Sometimes I water 3xa a day just for the hell of it. Coco is a Hydroponics so you don't want the coco to dry out at all

Also if your tap water is so bad you need the flora micro for hard water not the normal purple looking stuff it's like a blue I'll share a link hold on

Thx for the quick answer i am using micro for hard water i will get a new EC meter and will change my ph balance to 5.5-5.8 can i use a auto watering system ? With 4 sprinkles for each plant for the balance of water is it possible ?

Yeah if you have everything you need for self watering should be good depending on how much water comes out at a time you will want to tune it in for how your ladies drink. I top feeding by hand and fees everyday at least 2x a day. My girls love it.

Offcurse i will tune it in the first time i will see howmuch water i need to get a through off than i will calculate the amount of time the pump will work

Go for at least a 10% runoff off I belive. Not sure with a self feeding though at least 5% runoff that way it flushes out the old for the new. Good luck. Check out my grow journal in my signature below. ✌

Looking at your pics again and I would say it is ph problems and coco is way to dry for sure. After you change things a little within a few hours they will look better I'm sure.

Remember coco is notorious for Mag deficiency. That has been the problem with most of my grows with coco. I solved this problem with the 1 gram per gallon addition of Epson.
Good luck on your grow.
