If you could only buy one, which would it be.   ?     Mrs Bouquet

Chicken manure pellets or blood,fish & bone are all I buy. I make comfrey tea but rarely give that to anything other than tomatoes & cucumbers

Tomato food is good for anything that you want to flower well without putting on too much leafy growth; I use it on my bedding plants and tubs.

I like Maxicrop liquid feed as it contains sea weed extract which is beneficial to the plants especially when potting on as a little bit helps to settle them in afterwards.

Indeed, and you can get Maxicrop original, and Maxicrop tomato - which has the added potash for flowering

Also look at places like B+M, Home Bargains ot The Range for some very good offers, Doff also produce a good priced liquid feed.

Pretty much all plants use roughly the same balance of macronutrients.  The N-P-K three digit number identifies that balance in a fertilizer.  Any plant uses the N and K in roughly the same proportions, but much less of P (middle number); plants often do quite well with only 10 to 20 percent P compared to the N and K. The good news is that as long as you provide the nutrients they need, it doesn't matter if you provide a little too much P relative to the other nutrients.

So, a balanced fertilizer with all of the 3 numbers about equal is a safe choice for just about everything.

In the past I've used Doff blood fish and bone as a general fertiliser and worked well for flower growth.
Last few years I've used Asda own brand.

Just had a few boxes arrive on my last Asda grocery delivery.
