Are these seedlings you have started from seeds? Al

If they're outside in 4b it's not too surprising that they might be a little reluctant to grow with the kind of enthusiasm you'll see in a couple of months (temperature and photo-period). If the soil is well-made and you're not over-watering, the growth will come. Be sure to withhold fertilizers that derive their N from urea (which would be MG and most other soluble ferts) when the mean soil temp is below 55*.

Yes, I started them from seed. They've only really been outside this week since its been in the 70's and sunny. I was just curious really if focus on root growth would cause less foliage growth at the beginning of a transplant for a young seedling.
