I dunno McP... You want to water deep so the roots go deep, so I think measuring with your meter deep is the proper way. In a lot of cases the early fruits are more prone to BER and the plant outgrows it as it matures. There are so many ideas out there as to what causes BER that I kind of take it with a grain of salt... For me, it does seem to be caused by erratic watering. So far this year I'm really not having an issue with BER. Guess my new watering schedule (every 3 days, deep, by hand - lol) is working so far...
