Hi all, need some advice on what to do with some of my sprouts. In the pic below (No idea why it's sideways and I don't know how to rotate it) is a Marigold sprout that is having a hard time shedding its seed shell. The tips of the cotyledon leaves are stuck. Do I just wait for it to fall off on your own or do I need to help it out somehow?
Also, my Delphiniums are now starting to sprout true leaves. I tried attaching pics but they're too big. They are presently in seedling starter mix. I understand that I need to start fertilizing them soon... when? with what? how much? I have about 3-4 of them in 4-inch pots... Do I need to transplant them? If so, when?
