Hello!

I have had my seedling for a while now and I cannot seem to stop the leaves from browning. I've had 2 leaves fall off and I have read various things about browning leaves that hasn't made it clear.
I've kept it outside and then brought it in because I thought it was too much sun and it's still getting worse. I have tried watering it more and watering it less. I'm finding it impossible to tell what I should be doing

What should I do to save it and bring it to good health?

Please note I am a complete novice.

Thanks

Chris.

Leave it outside in the shade, not in direct sun.
Water when the soil feels/looks dry.
Wait.

This is important. Your pot looks very large for the seedling, which causes the soil to stay too wet for too long. This is dificullt to deal with for plants.
