@MickFoster, have you tried both tap and RO? When I first started this run I was switching from AN and peat to Lucas and RDWC, I thought I could get away with tap water but the best I could get was .5 ec, I ran it and had ca issues fast. At that time I was using micro hardwater and bloom, ended up going to RO and regular micro, one plant showed ca issues so I calimagic’ed them all. Anyways, had a couple issues so I want to try something else, what other Lucas formulas have you used? Did nova work different or better then maxi? Same shit different pile? I rather grow better weed with less, then so many do with so much, including myself in the past. I’m prob chopping a couple more plants tonight, I’m itching to get my next run started so I need to decide on nutes pretty quick. Plus I see my clones perked today, must of rooted.
