Confused as shit about my nutrients.

So I am in my fourth week of flowering and have just now realized I am completely confused about my nutrients..... fortunately everything is looking really good and crystally but I want to make sure that I get really good final product...

anyway the problem is that I Originally had started flowering with Botanicare pure blend soil pro..... everything was cool and I had gone to the hydro store and asked if there were any additives I can add to the nutes already and the women there gave me another product called pure blend soil with out the pro on it and it was 0.5 0.5 1 so its different from the pro..... went to another store tried to explain what I was using and the people there had no idea wtf I was talking about and I am not sure if I do anymore lol... I don't see any problems with the plants but I was thinking of keeping the nutes the same but adding beastie blooms.... What do you guys think? [h=2][/h]

The only advice I wanna give is keep it simple...as your experience grows so will your confidence and ability to test various nutrients and concentrations alike. If all is going well...keep doing what is already working and keep notes of every step along the way so you can fine tune it the next time around. Happy growing!
