With the feeding, ive gone both ways, feeding every time to every other time. I make batches of nutes in a 5 gallon bucket and just take from there every watering now. I also start at 1/4 or 1/2 strength nutes.. and when to feed them, i look at the feeding charts for the nutes and go from there, switching it up if need be. i find less is much more rewarding, you can always add more if you need it but once you over feed theres not much you can do.
