Well, I'm only repeating the hype Advanced Nutrients sold me on about the ph. I was absolutely having huge ph swings before. Using a calibrated bluelab ph pen, my ph is going in at 6.5, drifting up to 7.0, which I know is not ideal, but the magic of chelates and buffers and blah,blah,blah. No point using ph perfect and trying to adjust the ph. Before, using Flora I was getting truly hammered with ph drops. Starting at 5.9, drifting to as low as 4.5 in 8 hours! Which believe me, I know is a problem. I'd bring it back to 6, but over 4 hours in an attempt to lessen the shock. Tds starts 700 ppm, dropping to 550 overnight. Gets as low as 380 (yikes), topped up with either full or half strength nutes, mixed according to manufacturers directions (other than being half strength (8ml/gal)). Reservoir changed at least weekly, and i know i should do it once ive added back half the water (even that is pushing it) but that only takes 2 days, and im not changing it every 2 days. Just not happening. AN says equal parts Micro Grow & Bloom. Doesn't seem right to me, but I figure they know better than I do. Previously, I'd blame most of my issues on ph swings. I'm going to put these nutes to the test and hope they live up to half the hype. Generally I aim for 5.9 in veg, 6.1 in flower, but let it drift from 5.5 to 6.5, then bring back to 6.0 But this overloaded dwc is basically unmanageable otherwise. I'm dedicated, but I can't stay home 24/7 to monitor ph. I definitely bit off a lot to chew with this rdwc and leds. Growth is phenomenal, but soooo touchy.
