Purple leaves on my tomatoes

Sorry for another question,

I've noticed that some of the leaves on my tomatoes have turned purple.

There seems to be plenty of yellow flowers tho.

Its this something to worry about.

 

just ignore it. probably down to the cold. when it warms up it should return to normal. unless someone corrects me on this, although most plants tend to have a slight purple area where a side stem meets a larger stem, which is also normal.

 

I think,s it,s the cold too, don,t worry, they pick up when the weather warm,s up.

 

Best to keep them above 10C minimum, otherwise they stall and take a while to get going again.
