How do I make herbal plants healthy?

Hello everyone,
I recently bought some herb seeds online that are lemon balm (pudina seeds). Initially, I planted them according to the instructions and fortunately, the seeds grew but after 5 cm of the growth, the leaves are changing their colour to pale yellow.
So, may I know what exactly is going wrong with my plant and how do I avoid it?

We suggest that biotechnical approaches (for example tissue culture, micropropagation, manufactured seed innovation, and atomic marker-based approaches) ought to be applied to further develop yield and change the power of restorative plants
