The soil I am using is BioBizz All Mix. And the pots are the Fabric-based Smart Pots, so holes at the bottom should not be needed as far as I understand. I just buried the plants more as mentioned above.
I discussed this with my friend, but she seems to be having some issues as well.
The unusual thing I am noticing is that although most people are stating that the plants may be damping off, when I make a little hole to check how the soil is, it looks quite dry. I hope I can save this little ones, thanks for all your help!
