Take it with a grain of salt but what I learned is that I really don't worry about nutes etc. so early on. In fact it's bad. The crappier your soil etc, the better for seedlings. The only thing I do in the early phase is that I give CalMag SHOULD the plants at some point show signs of yellowing. (Looking at the nutes I use, PlantMagic Oldtimer Organic, a lot of folks don't actually use nutes during vegging AT ALL, because if you grow in normal potting mix it has enough nutes in it already for some weeks of vegging...and just worry about nutes once you start flowering).
That being said, your plants look great, they just looked a little over-watered in the beginning. I wouldn't give anything right now because they look perfect to me!
