I've gone over and beyond trying to get the blueberries to work. I made raised beds because the soil here is always too alkaline. I mixed in a huge bag of peat moss, peat humus, compost, pine needles, and layered the top with about 4-6 inches of pine bark mulch. That's not including the sulphur and fertilizer I added separately and continuously. Mine were doing really well until this last bout of rain. Then the chlorosis started. I thought maybe some of the sulphur and fertilizer had washed out from the heavy rain, plus it had been a month since I fertilized/added sulphur so I added more. I think this time I added too much and burned the roots? I've lost one bush completely. Another looks like this...

The other 5 are still chloritic but are also starting to get the dying leaves just like the first two. Pretty sure all of them are going to die and I'm not sure how to save them. I wish I could call a plant doctor like I call a vet.....
