yellow plant / coco grow problem

[tntntnt]

Hello , im new to growing so i was hoping to find a solution by someone
So my plants are now in 5th day of flower
they stayed for 4 weeks in 2 liter pots with canna terra but when repotted in 14l pots i put them in coco
now all my plants are yellow and seem to not drink much water
besides the ones that i put in the same medium as they were in the 2l pots , canna terra i mean, they drink water everyday and have a different progress
im working with mills nutrients and never checked the ph balance before
can someone maybe give me an aswer on
what to do
its more yellow than it seems in the pic
and i removed leaves because they were yellow with brown spots at the tip and curled inwards

You need to ph coir it should be 5.8 in veg you can’t skip it.

I can only help minimally in coir as I am mainly a organic soil guy

Questions that others may ask

Did you wash and soak the coir in cali mg before using it.

How far away is the light and can you post a pic in daylight. As it’s to yellow to see enough

For my own reference is that a hps light it kinda looks like one.

Btw by there size I’d say they need transplanting

I do wonder about what’s happening with the roots if they aren’t drinking every day or are they at least doing that

in veg they were in 2l with canna terra only
they already repotted in coir in the pic
stayed for like a week repotted in veg before switching to flower
no i didnt wash it
its far from the plant so i dont think its the light and yes its a hps one
i lift one up and the roots seem a bit better than i thought

Hey bud. There are a few things you must do when you grow with coco.
You must wash and buffer coco before putting your plants in it.

Maybe pop over to https://www.cocoforcannabis.com/
Come back after you have spent a few hours studying.

You absolutely must P.H your solutions! Be super fussy!

Right now I'd pull the plants out of the coco. Grab a bag of peat based potting mix
and finish them up in the potting mix.
Give yourself some time to acquire everything needed to do a proper coco grow.
If you leave them in un washed and buffered coco your going to run into calcium issues that will drive you nuts.
When you go pen shopping.
Get an E.C pen and a ppm pen as well with calibration solutions for the P.H pen. They are inexpensive out of china on ebay.

Are you watering the whole pot and not some weird circle around there stalk? Your root system looks under developed for what's up top.
