some of my tomatoes in the poly tunnel are going black on the flower end...seems to be on just 1 plant at the moment    but about 15 toms are like it   any ideas please

It's blossom end rot, usually caused by irregular watering - some varieties are more prone to it than others.

there moneymaker   and i water regular    so strange   maye too wet  or dry lol

[mumofstig]

Watering regularly doesn't solve the problem if they dry out a bit between the waterings

I think it's also a lack of calcium.

Usually the lack of calcium is down to the watering regime, in that lack of water stops the transportation of calcium around the plant. Throwing calcium at the plant is not necessarily the answer.
