Help on leaf deficiency

Having some problems with a few plants. Rather get peoples options..lemme know what ya think

Was wondering if this is a patasium problem or phosphorus not sure..

if you post more details and pictures I can help.
but I think you may be right
that is before I go help the old lady in the garden club with tomato horn worms lol

Looks like p issue. When plants start to flower they need a lot of P.
