they all have some degree of yellowing and necrosis with the major exception being the last one. those pics are from a couple days ago also and the first is still declining and the other 2 are about the same as they were. the run offs on the first three are all over the place. the last one comes in at just fluttering between 5.9 and 6 so i figure if i push my tap water up towards the high 9s i should get a better run off. they will all start the higher ph water this week so i should know for sure if it worked by next week since i already know down adjusted water is killing them.
