was on vacation the last week, so I couldn´t update the diary, now I´m back home.
08.01.: watered each plant with 4l of tap water+nutrients
10.01.: looks like the left plant is slowly developing a nitrogen deficiency, I´ll add some nutrients with the next watering.
12.01.: watered both plants with 4l of tap water + nutrients. (Hesi Bloom only for the one with deficiency signs)
