The color may be from the coco or from your nutes. Some nutes are just really dark, like canna and pureblend. Most likely it's a combination. I'd get in the habit of watering to runoff every time you water, and if that means propping up the pots over a catch-tray, so be it.

But that's what I'm saying I flush one to three times as much water the medium amount, every time I water. Which is about twice a week.

So please picture this 3-4 plants to water means one five gallon pail of rainwater to collect, bring in, flush threw, and dump out. Now multiply that by about 60 plants in flower and about 9 in veg, every three days. IF the water comes out really dark and takes 3gl to flush I don't feed it(should have said that before), I just put it back in to recover after the runoff is clear and the pH matches. But there are instances where the next time I go to flush/water that same plant I still get yellow/brown runoff, when it wasn't fed after it ran clear. In that case I don't feed it again.
