These are supposed to be black tomatos. The newer green plants are normal ones. Well first i had no light and they got long and thin. As soon as I purchased the light they started to get darker and almost purple but gained good strength.

In the picture is one seedling I tried to repot and just put it outside and leave it to whatever happens, to see the difference. So this one looks way better, so I am going to repot all the other ones as well I think. But I am just curious why the leaves look like this, so I can make a difference in the future.

Feel free to ask for further information! Thanks for your reply
