Hi allall I'm in 3weeks an 3 days into flower, i have been using ph down in every feed/watering due to my rain water where i live, I've now read up that using silicone ph down will higher the EC, i havent got a ppm meter or EC pen, and these tips have started to turn black/brown, im currently using mollases to try and cure this, can somebody explain to me where i should go from now, also do i need to have run off after all feedings/waterings to reduce salt building up? My ph is at 6.5 during all of this
