interesting!
will it benefit from some nitrogen? its been 2 days and the seedling hasn't growing at all. its stuck in the middle of leaf formation the first set. it seems strong, the stem. its just not growing.
You don't want the stem stretching too much. Mine grew about an inch a day so I had to replant. As for nitrogen, Id wait until it got a few sets of proper leaves first. I fed at 3 and 1 seedling curled up. The rest showed improved growth.
