It is up to you, but it wouldn't hurt to get in a grow without problems, by using 50% all the way. I did my first grow that way. I will also say that I haven't had a problem
since I went to full nutes (light/mod. light feeding for hydro has worked great for me)
so if you want to, go for it! I have seen growth with these nutes, that I don't think would've happened with other brands...not all, but having an entire regimen at your disposal is comforting...imho...lw...gotta go and edit some pix of my dead clones...a moth got in the res...story later.
