I documented my last grow in this forum in a thread titled 'Explosive Growth in Coco Coir'. Lots and lots of details of what happened in that grow.
It was successful - 28 ounces of Sour Diesel - but I fought nutrient issues all through flowering and never got a handle on it. Certainly I never understood the cause. So the purpose of this thread, hopefully not too long of one, is to figure out the probable cause(s) of the issue. Or maybe just the possible causes.
In a nutshell, the issue was that my runoff EC just get going up and up, even though I was watering crazy often - every 2 hours, with a gallon of runoff from each pot each time at peak. I would put in EC 1000, measure output getting up to 2000. This only happened in flower.
Before flowering, I built up EC in the nutrients per an average GH schedule. The EC of the output was always lower than the input. All that reversed in flowering - but why? I'm not the only one alarmed by high runoff EC. I can't figure out why it kept going up week after week. My ultimate solution was to drench the plants in RO water until the EC dropped to about the same as my input tank. But it then immediately started going up after that.
So - why?
