It's not running rampid or anything, but there was more purpling before this watering which stoppedonce they were fed, but i'm already exceeding the recommended ammount of Cal/Mg, so I need to watch as the pots dry out again. I was intending to use just pH water next but I think I'll have to add the Cal/Mg, hopefully it still acts as a nice break, without spreading. Am i really doing that good? Any idea the least ammount I can expect?
