Sounds fine to me but yeah, like Corbat420 said, the plants would devour all the nutes before the veg cycle is even half way over.
I would suggest Jiffy Plugs to start them. this is what I use for my soil grow
make sure to label (if you have known strains) I use tooth picks
and my Nutrients that I use throughout Veg and Flower.
You can get everything here for under a $100 and it really does make a remarkable difference in growth rate and overall plant health.
........If you are daring/ broke (or both) you can use ALASKA fish emulsion from wally world. It worked great for me but it's better suited for outdoor applications noting that it smells horrid [no carbon filter will remove the smell of rotting fish]. It's $10 a quart and the plants dig it. Like I said the Botanicare is great but if you're strapped for cash go for the fish.
