First off this is my first run ever. I think I'm actually still in good shape but am trying to stay ahead of any problems I THINK might pop up or THINK I have seen signs of. Ok so I ran into some burnt tips wilting/bubbling and am concerned I'm screwing up somehow. I've only fed to specification on nutes once and generally stuck to 3/4 the recommended amount otherwise. I'm in soil (happy frog) I'm using pro silicate 0-0-4 , medi one 4-3-3, have used Advanced Nutrients "bud ignitor" twice and will be adding Advanced Nutrients "candy" in cpl weeks once I start to see bud actually take shape and not just the pistils i currently have. Was feeding each 5.5 gallon pail up to 2 liters and was told to at least double the amount. I'll admit I wasnt seeing runoff often when I was feeding 2L. Stepped up to 4L feeds and runoff is there and not too little not too much. SOOO I measured my ppm pouring in at 180ppm and 6.0 ph with just water and this is what i got back Bucket A) 370x10 B) 289x10 C) 415x10 D) 427x10 I mix my water and nutes all in the same bucket and divide that amongst them. same soil same pots....why the various readings and not a general level across the board? Anything to be concerned about or first time paranoia?
