Grow slow and yellow cotyledons

I'd say it's too wet for the seedling. If you use fabric pots, don't water them from above, rather put the pot with his feet in water, so that the taproot has the urge to grow down to find moisture. If you water on top (maybe daily), the roots have no need to grow and if it's too wet, the roots rot.

Soil dug up from the hills will be low in nutrients and this is why your plants are growing slowly. Yellow cotyledons are of no consequence, they have no input towards plant health, vitality or growth. Their only purpose is to protect the growing tip as it pushes through the soil, after this they turn yellow, die and fall off. You will be much better off transplanting them into some quality store bought soil designed for vegetable/herb growing if you want to harvest decent buds.

You have a ph issue in soil Is my educated guess based on looks and information.

Soil from the hills close to were I live no trash or people around the location And mixed with perlite .. coco coir .. vermiculite.. and some germination soil with humus and very little nutrients that the germination soil contains .. as for the light a lampsoul lr1200 . 23 inches above canopy 20/4 light cycle
