Experimenting with some patio veg this year, and planted the containers up
yesterday. Obviously water's going to be vital, but as they're in
containers I'll need to feed regularly too.

I've planted:
Trough 1 - chile and pepper
Trough 2 - aubergine and mohican aubergine
Trough 3 - courgettes
Pot 1 - Cape gooseberry
Pot 2 - Tomato

I've got Tomorite and Phostrogen in my shed but wandered what to feed what
and when. Naturally the tomato plant will get Tomorite - but would that be
ok for everything, or should I use phostrogen for the others. Also when
should I start feeding them?

First time ever growing veg so this should be interesting!
