Zamnesia Runtz photoperiodisch

they look ok, would not stress about anything at the moment.

Bit too long........move your light closer.

They are a bit longer then I like to see, When this happens and they stretch a lot its from lack of light "density" and wind. Light helps tell the seedling where it is in the world and less strong/dense light means its not in a good spot and they need to stretch to get to better lighting and wind helps it strengthen the trunk so it does not snap from stretching to much. Support them with a skewer or stick till they get bigger or slowly give them a gentle breeze so they can build up strength and give them more light to prevent the excess stretching. Good Luck!
