@dex I think they look pretty good. Others have had issues w FFOF being too hot for seedlings but yours are past that stage. Pay attention to their new growth. Mine are in a Super Soil and I have two plants that their new growth has slightly yellow tips but they are growing well and the others don’t seem to have an issue. FYI - I am growing two Sour Diesel as well - sprouted around 1-16 if you want to compare or follow my Journal.
