Mid season feeding for a Himalayan Giant blackberry?

in Fruit & veg
I have one of these slightly vigorous, large, blackberries in my back garden.
I have had the first half of the first flush of berries - about 2kg and I need to gather some more tomorrow.
There are still plenty of yet to grow berries on there.
My question - is it helpful to feed it now, and what to use, and for how long?
It has been having some seaweed feed and some tomato feed on occasions.
But I am a novice at this fertiliser lark, so any comments would be most welcome.
Cheers

If it is indeed a Himalayan Giant, I hope you have appropriate clothing to wear when it needs pruning. I read somewhere that full motorcycle gear, including helmet and gauntlets, works well!
And yes it is a Himalayan Giant - has been known to go over the fence and nearly to the top of the pitched roof of next door's garage in one summer.
I wear a pair of these "Wilko Rigger Gardening Gloves", which are inexpensive and high quality for £3. Review well - better than the "gauntlets".

Used to have one at a previous house, so my mum bought one when she was doing this garden. It has it's own support framework which is about 5 fence panels long.
I'm a fiend for blackberry vinegar.
I'll definitely have a go at that - thanks for the idea!
PS - I agree no need to feed blackberries now. I give mine a mulch and some blood, fish and bone in the spring and that's it for the year.

My differences:
1 - I use about 3 times as many blackberries and a third less sugar. On the batch last week that was 1.5kg blackberries to 500ml cider vinegar. The finished vinegar should be like purple Quink. I should get about 2 litres from that. If necessary it can be diluted later.
2 - I use a potato masher on the blackberries so more will fit.
3 - I let it steep for at least a week.
4 - When it has drained through the muslin I wring out the blackberries in muslin like a flannel as that generates a *lot* (perhaps 30%) more juice.
5 - I keep the pulp to make a chutney.
6 - I use a saucepan or measuring jug not the earthernware dish.
I have blackberry vinegar on pancakes mainly, or with an extra couple of Yorkshire puddings for dessert.
The flavour can be adjusted by adding more or less sugar when simmering the vinegar at the end to taste. If balanced well it is a delicious sweet and sour flavour.
I really like the sound of that.
I love a good balsamic vinegar and stuff like pomegranate molasses and blackberry vinegar sounds right up my street
