Been fertigating twice per day with lower EC solution, around 900-950. The run off was creeping upwards towards +500 again for around 1300-1500 EC. Not a bad number in my opinion but I don't like the wide spread of input to output EC. Also, elevated these lovely girls for better air circulation. Eventually, I will install an automated runoff pumping system with a condensate pump. Currently, I have to move the plants out to fertigate, remove the old runoff and then return the plants. I like checking on the plants every day but moving the plants is getting a little old. Hopefully, the work will pay off!
