Good advice, scrubby....my first go I worried about everything....when there was absolutely no need...I'm only on my second grow, but the stress is completely gone and replaced with trust and respect....that's a good place to be....I see folks all over this site scrambling about diagnosing nutrient burns or deficiencies while the brix folks nit pick about how much of this and how much of that while our plants thrive in spite of us...it's comical actually, but my sense of humor is left of center...ahaha....good day to all
