Group 3 clematis feed

My group 3 clematis are in full new growth mode at the moment, but do I keep feeding with a high nitrogen feed or do I change to a high potash feed. Thanks.

    Soon as the flower buds begin to form I change to a high potash (tomato) feed, Pete. Before that they get the same balanced fertiliser as I give the roses.

    I give a heavy mulch in early Spring, plus a general shrub fertiliser.
    From May I give tomato feed every 2 weeks.
    There are ashtrays of emulsion,
