1st picture it looks fine other two pictures look useless. Looks healthy in the 1st picture. Doesn't look like very good soil. What soil are you using?

OK. I'm a soil grower. It looks healthy in the 1st pic, maybe a little bit of yellow.
When a hydroponics person shows up to chat about coco with you they are going to want to know what fertilizers you are using and what quantities you use them in and how often you use them. If you list that below you should get some help.
Do you PH your water before you water?
Do you have an electrical conductivity meter also called an e/c meter or a ppm tester?
These are both used when growing in coco.

Worry more about the color than the slow growth. It is just a baby with few roots underneath. It needs to develop its roots before it really takes off.

Very thanks for ur replay.

I use 1.5x1.5x2 seahawks tent grow it.
And i have Ph tester , but I don't have PPM tester . ( If need i can buy right now )
When i watering PH always 6.0
I use general floranova 7-4-10 , I didn't used armorsi 0-0-4 yet
My growing room temperature is high a bit, sometimes going 30+ ( now 27~28 around )
I using air conditioner get down temperature.
Lights : 16 on / 8 off
My bulb is 600W right now , but i use ballast change to 400W now.

Im just growing with in 100% coco coir , ( No fertilizers )
If it possible i want change environment ASAP
But this plants is baby now , So im just worry about if i change coco that maybe get shock and die...

I should have known more about it before i started, I regret it.
What is the best way to think about this right now?

I am very sorry about my bad english..

thank you

Nice info, You should get some help soon. Do you have an E/C meter?
If not you will eventually need one in coco.
Fertilizer info. They will need to know how much you use in ml per liter of water when you fertilize.

Good. It will give the other coco growers a lot of information about your water and your nutrient feedings. They last a long time and are easy to use. A good one in the US probably costs $30-$40.

Do u know When is best time to change pots? if i change now is very dangerous isn't it ?

Do not change pots yet. It will be fine in that size pot for now while we see what your water E/C is and your fertilizer E/C. I'm not a coco grower but I'd guess if it remains healthy and grows it can stay in that pot for at least another 5+ days so there is plenty of time for that.

Its turning yellow cuz coco has no nutes(soilless medium) add some cal mag to your water which contains N as well or add a light dose of nutes and water it lightly, foliar feed if you have a spray bottle

Sketchy doing all that to such a young plant. I always believed they had plenty nutes until the cotyledons wither?

Thats silica not cal mag - you need cal mag in coco as the coco itself absorbs some of the calcium and your plants will start looking bad early.
I strongly suggest you get some type of calcium, a bottle of cal mag is cheap and can be found in most places or order it online.
I use botanicare but any cal mag would do

One more thing - i didnt notice any perlite in your cup, poor drainage and overwatering will cause plants to stunt and yellow as well.
