Tripdog, I am afraid that your soil has got very acidic by now, that is why you see problems. These problems are very serious and will reduce yield.
Maybe would be good if you know outrun water PH, to get some picture. Be sure that you get outrun from the bottom and not from side holes at the top.
30 days is just enough to build up problems in soil, before everything was ok and so nice and beautifull. I have seen it so many times.
Good Luck!
