should i stop or add more plant??

I would say don’t stop add more plants. If you have fast growing stem plants use them for more filling in. Once you start to plant a tank it is normally better to try to add a good amount because of the nutrient uptake of plants. If you don’t balance you’re lighting to nutrient uptake of plants you will end up with a lot of alga that will be hard to get rid of unless you add more plants.

It is normal recommended when starting a planted tank to plant a ton of stem plants (faster establishing) and slowly change out to potted plants (slower establishing).
