Issues with new plant, any help appreciated

You probably need to use more than fuck all and then they'll look greener. Yellow is always a deficiency of something either being from under-feeding or PH being off in the rootzone. Yellowing can also happen from cold temperatures, say below 70 °F or 21 °C especially in VEG.
Doesn't a toxicity of one, also lead to a deficiency of another?

Here is the path I would take. You need an accurate ph meter and ppm meter. These two tools kept clean and calibrated and stored proper will allow you to learn a lot and will be very important. I use the 500 scale for my ec to ppm conversion on my bluelab pen.

Get some coco, soak it in clean water for a day then check the ppm of the water. I like to bring down my ppm of my compressed coco it usually is around 300 and I bring it to below 50 with my ro unit.

This is the wash process. If the coco is fine I try to sift out small coco particles when washing

Next step is charging
Add desired nutes, I like 400-500ppm. I dose extra cal mag as well, coco naturally needs more cal mag and if using leds you may need extra cal mag. I use half or full strength of the manufacturers chart when charging the coco.

Now I wait one day and check pH. Adjust ph and once stable it's ready to strain and use

Here's a great video on how coco coir bonds with K and why these steps are important. I enjoy using 100% coco. I do have plans to reuse my old coco too, as I hear you can easily re use it. I like the brand canna , the bagged stuff is nice but expensive, the bricks are much more economical and easy to store



After preparing the coco, you take your plant you have and try to rinse the old medium off the roots, transplant into your new coco and you're all set

You never want it to dry out
Ph 6.0 water
Aim for 10-20% runoff to prevent salts building up

Thanks very much for the help fellas. Definetly isnt too cold, around 22-25 degrees celcius usually. Next feed i will up the nutes a bit and see how that goes. Once i repot, since its 80% coco, may aswell repot into just coco hey rather than someone suggested to use soil? Happy to learn to work with it, gotta learn shit somehow

Honestly, i dont think theres something to worry about here, yellowing of the first few leaves as the plant matures usually happens, just watch out if yellowing catches up the whole plant. if i had to bet its over watering abit, since as someone said coco and soil dont mix together so the soil might look a bit dry on the top while you water it often as not needed. I usually do organic on my seedlings with no nute feeds. Just top dressed your soil it with some down to earth seedling mix 3-3-3, put some Mykos in there as well, and just feed it some blackstrap mollases. Its all about the roots man. Still waiting for my international orders so i had to deal with some home made soil earthworm castings, Spagnum peat moss substrate which is the soil available atm.

Some plants had yellowing leaves since i have to force water them due to a 3 day leave that i wont be seeing them. Or it could be the PH lol but i never once check my PH.

All I'm trying to get to you is, if you go the coco route, you want coco mixed with another inert medium , not soil. When going to transplant or maybe soon before it becomes rootbound you can just rinse off the old media to avoid hydro problems. If you do go hydro, you absolutely need ph and ppm pens, they will help you a lot.

If going the soil route, id still wash off the coco , and mix it in the new soil medium when I transplant

And after a couple of days no more yellow. Sometimes its just too much watering. Less yellowing now after a couple of days since i forced water it.
Mine is also a little less yellow after not watering it. mightve had one too many hot ones and watered it too much without realising

Glad that worked out for you, most of the times its just the basics and we over analyze what went wrong. I would suggest to go organic in seedlings later on if you wish to go chemicals make sure they have a stable root system, Get some MYKOS and down to earth products it goes a long long way.
Carefull overwatering a few day old seedling though.
