How can you tell if you have a marijuana seedling
(plant), I've never grown one before and need to know what they look

will have to wait until the plants develop a bit more. Below are
some pictures that may help for comparison. Marijuana seedlings tend
to have a first set of leaves that are rounded and then all the rest
of the leaves tend to have jagged edges on them.
