Hi,

Have a dozen dp Blueberrys 5 weeks into flowering that are having a few problems. A lot of the leaves are starting to yellow and some are developing brown spots on them, wilting and falling off. The more seriously affected plants are the larger ones that are a couple of inches bigger than the others. The yellowing is starting at the bottom of the plants and working its way up. Any ideas what it could be? I'm guessing pH but could it be a nutrient lockout too?

Cheers
