Using DTW autofeeding 7x daily in coco/perlite mix.
Late in flower stage now.
My EC is consistently higher in runoff than input, sometimes over 200 points if I don't water 'a lot'. A couple of times I've dumped 4 gallons of runoff back into my 30 gallon reservoir along with a bit of RO to lower the EC where I want it.
M question has to do with the quality of the runoff EC - is it likely to be in the same ratio as the input EC? Or would I expect it to be disproportionately lower on something like calcium or magnesium, or the nitrogen got sucked out more (or less) than the potassium, etc? I put a LOT of runoff into my houseplants and yard these days, and I would be very handy to once a week just be able to re-use a 5-gallon bucket full of runoff into a half-empty reservoir.
