GrowCNanswered grow question 4 years ago I don't transplant. All my seeds go into the soil in their forever pot so I say you didn't pot too early.
As already mentioned don't over water your young plants. They are tiny in a huge pot so it's easy to give them too much. Their roots will go much deeper than the plant is tall so even if the top of the soil is dry they can still get moisture surprisingly deep. I also like to water the soil around the plant, even when it's tiny to encourage the roots to grow outwards and use all the soil in the pot.
