I Am new to the site and would appreciate some advice I'm growing grape ape they germinated 6 days ago and I have potted them in cups size pots. For being the same strain some have started there 2nd lot of leaves and are nice size and 2 of them are still small and only just starting to shoot 2nd lot of leaves??? I'm confused why they are slower? Oh and another thing on one set of leaves on slow grower one leave has come out and other hasn't?
