Welp, about to leave town. Getting everything all set up for the friend who will be watching over the babies. They go into flower tomorrow at 6 AM and will be operating on 12.12 from there. I bought some Bloom nutes, as well as MOAB Mother of All Blooms additive which is used for the first week of flowering I am told. Am I incorrect in saying that this stuff will not show up on the PPM meter? I am going to give them 400PPM to start because they were just flushed, and then throw some of this in...which would obviously raise the PPM but the pen won't be able to detect, right? That's what I was told anyhow. Should I use the full amount as directed or have you guys done less in the past? Any info is great!
