Looks good. But you shouldn't be watering at the base of your sprout. It contributes to damping off. Try to water around the drip line. That's to say at the edge of the leaves. This will encourage root development. Let her work a little for her water. You'll have to water more often, just less at one time. Use a squirt bottle to make it easy.
I've never used
BioBizz, but a 20% run off at this point in the development of your plant may be excessive. But I stand to be corrected. A 20% runoff may be in order after 3 weeks, but only around the perimeter of the pot (from the size I'm assuming you have.)
