I know some could care less about runoff and get along just peachy. Id like to get there, too. I'm not too interested in chasing runoff, but maybe better understanding what the numbers can mean when symptoms lead me to check, I guess.
Some junk in my head:
For whatever input EC, the runoff could be say ~0.2 higher and the plants could still be feeding just fine. In this case I'd assume the ec rise being due to the salts concentrating as coco lost moisture between feeds. Increased water volume and/or frequency could combat this if even necessary. Yeah?
Suppose the EC is rising to x due to salt build from lack of runoff or the plants just not feeding. Outright flushing aside, continued watering at x-y should bring the EC runoff down to x-y. Right? I think I've verified this for myself recently, just checking that I haven't completely lost the plot.
If feeding coco daily with 6.0 pH'd feed wouldn't each feed reset the pH as it does the EC? I have a few plants that are consistently
giving back 5.3-5.6 pH runoff when I've been giving them loads of 5.9-6.0 pH'd feed, +40% runoff, every 18 hours. I get that runoff isn't a perfect measurement, but is pH more susceptible to inaccuracy than EC in runoff readings?
Appreciate any thoughts/corrections. Thanks.
