Ah, now that I see it you could probably put the nitrogen stuff away and just use the Baby Bio for vegging. 10.6 - 1.9 - 1.4 is much better than straight ammoniacal nitrogen, and since it's organic based nutrients there's less a chance of burning the plant.

Don't feed them if they're only seedlings. Instead, wait until they're about three to five weeks old, then feed them a half recommend dosage of the Baby Bio to that amount of water the bottle lists.

In the mean time try looking for some flowering foods, maybe something organic based. You'll need something with a higher phosphorous rating and with as little nitrogen as possible, so go with a higher P and K for the flowering food. I recommend bone meal, kelp meal, or maybe even a guano high in phosphorous and potassium.

Oh, and you answered yourself with that "the bottle says 'contains organic matter', is it organic" question.
