How are you estimating the resulting EC?

@2com my grow meister

For a new recipe, I start with a little less RO than I think I need.

After everything is mixed I check the EC.

Add more RO as needed to dilute down to my desired feed EC.

Then adjust to my desired PH.

Done deal.

Future mixes, I learn more precisely how much RO to start with to hit my target EC. Rather not dilute.
 
Did a reorg. Needed my raised gravity drain trays installed since I have a combo of SIP Octopups and fabric DTW.

Several of my early Octopup deployments are not dropping roots. My bad.

Decided F it. Converting them to top feed dtw. Lol

Ok. So in other words, it's not a guesstimate, it's a measurement from a previous batch. You just record the EC of a mix at that strength (ie with those numbers).
