russrahlanswered grow question 4 years ago Hard to tell what your dealing with without some pics and info on what you have been doing. I don’t see a grow diary for this so hard to tell. Im usually sitting between 0.5-0.7EC at that stage. But again, there could also be other factors like ph, water temp, light distance, air temp, etc. When growing hydro all variables are more crucial then when in soil, there is less room for error in hydro.
