600ppm / 1.2 EC in, 750ppm / 1.5 EC out.
pH 6.1 in, pH 6.4 out. Lowering input to 5.7. taking another reading in 3 hours and mixing some top off to the reservoir.
I normally make 3-5 gallons at a time since bigger volumes are harder to work with. I mix a 3 gallon stock solution every week at about 5.0 EC that I use to dilute to desired strength.
I mix 75ppm potassium silicate, about 30ppm elemental silicate, 150ppm Calimagic and stock solution til I reach 600ppm/1.2 EC and then add 2ppm residual chlorine. I dip 4 fingertips in the cup and clean it in the solution.
She's being fed 5 times a day with no drybacks. The top layer stays wet at all times. I'm growing in hydro growing in coir and about 40-50% perlite. It took me many years to grasp how to optimally feed in coir and how I should think of it as a medium. It was after running DWC for 10 years and then going back to coir that I understood how to properly cycle the media and nutrient solution and feed coir or any soilless media.
I had great results back then to in soilless but I did a lot of mistakes and errors looking back on my early growing years. Thought I understood more than I did. Probably still do but I feel old and I imagine and believe myself to be more humble and wiser these days, lol! It's better to be an open book and accept your own faults and limitations to easier see room for improvements.
