Ethos early lemon berry

I work away 2 weeks at a time so been a bit more difficult not being around to lst as much as I’d like but my top off tank has been working great. My res ppm is 740ish when I leave and 780ppm 2 weeks later when I return. Ph dosnt change I’m using the perfect ph from torus seems to work great. Roots are heathy using the sensizym and my solution temp runs around 20-21 Celsius. Going to going training for a few more weeks then flip into flower.
