Q4 Fertilizer

I've just bought some Q4 fertilizer I was told it was very good for both veg growing and flower growing and as I haven't used Q4 before can anyone give me a bit of info when would you apply Q4 at the seedling stage or larger plants and how often would you recommend feeding the plants including both veg and flower
I have used liquid feed in the past but not this

Hi,
 I haven't used it but i think it's way of using is similar to Growmore (but for different crops). So you'd hoe it into the surface before planting & then sprinkle a bit round the plants as the year goes on.
 
Looking at the N-P-K Growmore is 7-7-7, Q4 is 5.3-7.5-10 . So higher in potassium, meaning good for fruits and flowers.
Edited to add;  I tend to use liquid feed for tomatoes & strawberries because those are in various containers here due to challenging weather!!
