And for the Vanilluna -

all same plant, last pic is the underside of the leaves. When the second set of leaves came out they had purple coloration, this picture shows the purple color of the underside of the leaves. It could be genetic seeing in how Vanilluna is made up of multiple blueberry strains, etc.. Don't think its a deficiency because all of the plants are in the same medium and drinking the same water and this is the only plant w/ color!
