Ok so my seedlings have PH lock out at the moment and its because the PH is obscenly high, something like 8.5+ and I have NO CLUE how it got that way.

I've been flushing them for the last half hour or so and the ph just won't drop, and I have no clue why. They are in a manure/perlite mixture and I've been flushing with water ph'd around 6.8, anyone have any idea as to why the PH is staying constant at such a high? I've probably run nearly half a gallon through each of them already and they are only in regular sized plastic cups...I'm seriously stumped here.
