Did you ever figure out whats going on? I have a very similar problem your leaves look just like mine. I dont know if u got your ph tester but i got a really good one very cheap on ebay. i get a lot of stuff from ebay that you can get in a nursery as to not attract attention. But if you figured it out i would appreciate any info u can give me. and what steps you have taken so i dont repeat unecessary steps. I am thinking ph my run off i tested yesterday was 5.5 in soil.
