Hello all I'm a little unsure of when to change up.nutes. Sensi Grow Advance Nutrients to Sensi Bloom?? I fed yesterday the Grow & im wanting to flip em without any fuss. I did a little defoliation also. I've read it's ok to flip now but others say to wait. Keep in mind a lot of these posts are from mid 2000's so I'm sure things have changed a bit. Thanks in advance.
