HB DC Active Member Jan 9, 2013 #23 I don't think it is lockout of any nutes... unless there is a serious PH issue! Lockout occurs when PH is not normal! Can go both ways! Here is a lockout graph (a must know for hydro but not really a big deal with GOOD soil) View attachment 2472916 Good soil is around 6-6.5 PH - IMO.. What nature provides through seasons (outdoors) must be replicated indoors!
