LSY, the plants don't need much N during flower. they need only a small amount...and seeing as how yours are still nice and green i don't think they need the N. worry about the P and K. if you have to hit them with your 20-30-30 (or whatever) go with about 1/3 strength and then don't feed them that again.
how long have they been flowering for?
i just shot you an email. so get back to me and i'll get that stuff out by next week at the latest. i'll try to get it out tomorrow though.
also for the big bloom or tiger bloom check out
here. they have the big bloom for $9.90/quart and the tiger bloom for $13.90. they are located in twinsburg ohio so hopefully shipping won't be too expensive.
your plants look really good. don't get discouraged. indoors is slow, especially under CFLs!
