Okay, so one of the things I'm now monitoring closely is TDS. Never really cared before because it was too much trouble! lol
The week 3 flowering plant was even after a day, meaning that it took in the same amount of water and nutrients throughout the day, so it's balanced well.
The week 5 flowering plant, however, dropped by >100 ppm. This means it needs a little more nutrient, right? So I can add a little bit extra of something. What do you guys suggest I add? I am leaning towards more Koolbloom which is 0-15-15...
