Oh, they are contradictions for all of humanity, ok? The fault lies with your set. Please make major adjustments, and test every adjustment. And of course, please recognize that customer service is doing their best, but they are after all minimum wage phone reps, and your best source is the original manual and experience. If you seek for the answer in the manual, you will find it in your experience; please note that you must experience, or they like to say around here "are you experienced?" not sure why, but that's what the master growers I'm reading say with a smile. You cannot find God all by yourself (your ship should be at sea). You have to find God all for yourself, and you are surrounded by Him right now.
Presuming I need to find God. Of course.
