What type of water are you using for it? Is it grown indoors or outdoors?

I'm using well water from outside, and it is indoors

Better measure the TDS of the water. It needs to be below 50. Also, the plant won't get enough light indoors.

it needs sun and use destilled water. It would be normal if the little plants were nice and green, but they seem burned too. The big ones get burned down when the little ones are in growth.

I noticed the perlite on the soil. Rather than regular potting soil I use a mix of sphagnum moss and peat moss. Some potting soils have fertilizers mixed in, and that's a no-no. ;)
