I was having a serious issue with blossom end rot on my tomatos last year so I purchased a supplement the BER is not as bad as last year but I'm still loosing some tomatos to it? In north central Pennsylvania we have been getting a LOT of Rain! The tomatos in the self watering containers are what's affected. Any idea how to fix this calcium deficiency? Can I double up the recommend dose of the Cal Mag? I'm starting to think something could be in the well water because the plants that get mostly rain water are doing better not having to use the well water the past few weeks. See photos of what I'm using, the lime was for the self watering containers per the instructions and worked fine in South Carolina.
