D.21 had to switch over to RO water, tap way to high couldn't get enough feed in with out blasting out the tds/ec. Plants are a bit small, if they don't turn around in next week or so I may scrap and replant.
D.23 Topper off 2 gal ro, unusual low humidity weather, should correct itself shortly
@TickleToast, they've treated me well so far. 4th run and still seem good to go. When these go out, I'm going migro array. Same diodes but spaced out farther allowing closer hanging heights and good even spread. With my current hlgs I'm getting mostly 870 to 1050 umols with a few 700 spots, but I am not using my full grow space.
