No, I'm not using self watering containers. They're 17litre hard black plastic pots with drainage holes at the bottom edge. I just purchased a soil moisture meter and discovered that the soil is holding the moisture in for much longer than I expected. It still reads >4 up to 4 days after watering (4 being the wettest - and according to the instructions on the meter, 4 is also what tomatoes prefer for soil moisture level). I also purchased a PH meter and found that after my dolomite slurry treatment, the soil measures a PH of 6.5 - 7. I also measured the PH of the manure (still have some left) and it also measured pretty much neutral. I've started adding a liquid calcium/magnesium supplement called Mag Cal. However, I'm not very clear on how often and for how long to add it to the water that I water the plants with. The instructions on the bottle don't say. It only says how much to dilute it for a treatment. So far every tomato on every plant has BER and I have 14 plants. At this point only the first tier is fruiting so I am praying that the second tier will be ok. I guess only time will tell!
