Cotyledons and first true-leaves turning yellow on young seedling; Advice?

Hello everyone! This is my first time trying to grow indoors, and for some reason my seedlings leaves are getting yellow
and brown at the ends. This usually starts at the ends of the cotyledons and moves inwards (eventually effecting the lower
true-leaf on this plant). Any advice or tips on how to breathe some life into these plants, or improve my technique for next
time? Thanks all!

EDIT: I am using seed-starting soil as the growing-medium, and am watering it with room-temperature
tap water about 1 time every day or soCrispy_Weed.jpg

Try transplanting them to something bigger. Make sure ur water is 6-6.5 ph

I start all my seeds in a container I can add soil to a couple times till the plant develops
No need to repot that way

Figured out that the plant did need to be transplanted into a bigger container; The root system was getting too large for the clay-pot it was in and the health of the plant declined as a result. I transplanted it today and hopefully it'll recover - Thank you for your advice!

personally I did not see pot size issue. I agree Joe blow .lack of light.
the plant itself had no root bound issue until the plant is as wide as the pot itself. it called 5h4 drip line. the plant will only grow as big as the container with out daily watering as in hydroponics. ( that's the only difference really. )

that is a tiny plant with no true leaves even 4hr last thing it needs is a bigger pot. the little one will stay more aerated to. check light level . a free light meter app is available on app. store. 1500 footcndles is very reasonable for a seeding. footcandles or FC is the intensity of the light. the actual volume of photons .the PAR spectrum is just that. its 4he spectrum or quality. it's also important but so is intensity.
they csnt work with out each other.
anyway . 1500 footcandles. light . water lightly until it gets a few true leaves and then replant. good luck

Yea man. Sometimes it is. I ran into that with one of my current ones. And as soon as I transplanted it it grew. Does look a little short and wide tho but maybe I transplanted it to deep.
It’s the middle plant in the picture of all 3 of them. Other pics is of the one of speak of
