Leaves turning yellow, also the brownie pot plant is growin like too tall/ small leaves? Help me guys please!

what space between plant and light ? i see praying leaves there. Maybe she stretching to find better light or could be too much light intensity if their serration edge pointy ups. you can find light measurement app on your cellphone, It might be not accurate but it help me a lot, in this stage PPFD should be around 300. I still learning by the way. Good luck!

Yellowing of leaves in such early stage might be an indicator of N Deficiency. If you see small white or yellow dots on the leaf it means that the ladies are craving calcium , also later stages of calcium deficiency will make the leaf to curl up like a taco. I’m not an experienced grower like my name suggests 😅… but I went through something similar and ended up feeding extra calmag to my plants and it hurt them real bad!! Just gradually increase the grow nutrient that you are using!! It should be fine! I’d also suggest for you to wait until some experienced growers answer this query.
