Doc, I have a question for you on the CRF's. I started a new grow and have been using Jackson & Perkins Rose food (it's labeled by J&P, but made by Dynamite, is 14-5-10 w/ micronutrients). The amount of the CRF added was right at the instructions on the package, which called for 6 tablespoons in a 3-gallon pot. The medium that I am using is Sunshine Mix #2 (no added nutrient package) cut 50/50 with perlite, and a bit of lime added. I have been sporadically testing the runoff and am confused about my findings! The EC, as read on a BlueLab truncheon, vary from early readings of 1.4 to 1.8 to my current readings of 3.2 to 3.6. There have been no additions made to the nute levels in this time period other than a weekly application of a more complete micronutrient package. The plants, which should be burned to a crisp, seem to be happy as hell. I was wondering if you had any light to shed on this, or am I just suffering from too much information? I appreciate any information that you might have, and I always enjoy reading your journals.
