You're going yo get different answers more than likely.
My 2 cents is no need for any run off.This is the first feed and you're feed is low so you have nothing to get rid of yet as far as any kind of salt build up........which is the only time i would water/feed till run off.
Check out the coco section.Lotta info to get ya goin in the right direction.I see you said you are using the grow bottle along with your micro and bloom??Are you aware you can do with out the grow bottle and just use the micro and bloom?Not saying not to use it......it's your smoke,but it isn't needed.
Sounds like you are off to a good start. There is no real need to have that much runoff. Just make sure you don't let the medium dry out, keep your solution ph 5.8-6.1, and make sure you are supplimenting CA/MG correctly. Look into H3ads recipe. Lots of people have good results using it.
