@BigSm0 thanks for the input, much appreciated. I understand all the other parameters that go into stellar grows & truly feel I have those nailed. Consistent 8 to almost-12 oz yields off single-plant auto grows attest to that. Even the "fails" I have, by most growers' standards, are very good at 4+oz. yields, again off single-plant grows. But I've done better & want to return to consistently hitting 8 - to - 12 oz yields for each round, and there are others who even beat that. I can't do that with my current lights and grow methods. So I have to get over "what I know" & figure out what I don't know. I'll be dropping an order to you early this week. I don't want to change too many things at once, but I am interested in this new nutrient line you've spoken about. If you can post particulars of where to get it I think I'll work that into my schedule for this year. Maybe grow with current nutes under your new COB's and new nutes under my old lighting systems. Change only one thing at a time that way. Thanks again, You're a good Man to have on this Forum.
