Timing for potting up seedlings
When you start seeds in soil-free medium (or nutrient free), they say to transfer them to some soil with nutrients after the first set of true leaves set. For my brassica (broccoli, brussel sprouts, kale) and fennel seedlings, I neglected them for some time. They had used up all the nutrients from the cotyledons and were essentially starving. I started two extra broccoli plants for the community garden a week or two after the first set and noticed the huge size and growth difference after potting them up. I'm not sure if the first seedlings are stunted forever...hopefully they will catch up.
