If you are flowering, that's still pretty high in nitrogen. That combination sound like a house plant flower food. If you can find a 0-13-14, that's what you need during flowering. DO NOT add fert with every watering. If you wanted to do it once a week, mix it half strength, and even then, I'd be a bit weary of it. Sometimes 'less' can actually be 'more' where chemicals are concerned...B
