Trying to wrap my head around the run-off numbers: Solution 1.5 EC / 5.8 pH IN DSD1- 1.2 EC / 6.0 pH OUT DSD2- 1.4 EC / 6.0 pH OUT DSD3- 1.5 EC / 6.0 pH OUT WC - 2.2 EC / 5.6 pH OUT What's happening here? Why so different? Plants all look great but need some explanation please!

ive had situations like this.. i believe that the wedding cake is not feeding as much as the others.. salts are not being absorbed and therefore lingering in the soil/medium and that also drives down the pH. especially when one strain is showing different run off than the others.. all the dosidos are similar but not wedding cake. thats my interpretation from experience

Meter's cally'd, every plant gets the same drink. I literally just ran a gallon of 0.5 EC through it and the run-off came out at 1.7 so I think it's either I forgot to rinse the catch dish or some salt build up was coming through...OR I left to dry too much..I think the others need slightly more nutes (but not much?)

Have you calibrated your ec meter ? cause that just does not make sense sorry if it sounds patronising.
