Because of the light height on the first week I'm not sure if they're at their right stage by now.
I feel like they're a bit small for 9 days.
Any suggestions? Anything I can do or maybe I'm worrying for nothing?
Nothing you can do, leave it and she'll be fine, plants are hardier than you think, the more you fuck with them the more damage, usually, you will do, especially as a first time grower, chillax bro ;)
