So I just started growing my first plant, it poked out of the soil 3 days ago and is currently about 1/2 inch tall. For some reason the stem is half green and half purple, and has white hairs all over it, is this normal? could there be a problem? Sorry, I'm just a little paranoid because i've been spending a LOT of time setting up my grow room and whatnot, and I don't want my first plant to die. thanks in advance!
