Hi!
Welcome to the avenue
As you are in the UK(I believe?) you could also go with either Beaphar Care+ or NutriBird as those are more commonly available I believe and in my opinion good as well
NutriBird does have sugar and depending on the cariety color, but my birds only ate those in the beginning. I and planning to add TOPs pellets(those don’t have vitD3 so shouldn’t be the only pellet) and caitec overnfresh bites as well for variety. I make my Own seed mix, have three commercial ones(I can look those up when I get home, one is Teurlings, one from Witte Molen, and one I am not sure) for foraging and treats, I love
Parrot Paradise for their great mixes personally. I love their flower seed mix most!
My birds also get chop, I buy a large variety of vegetables(you can start with a small variety too
), dark leafy greens, red and orange veggies and Some that I know are great nutritionally have my focus. I try to include at least one veggie from Each color and a few different sorts of berries(blackberries are an all time favorite!), and Some grains. I have coocked my grains the last few times. I would like to use beans as well but haven’t gotten that down quite yet. I chop Some herbs up for them to add too, but most of the time I give those fresh(I freeze my chop). Great to know, birds can eat peppers because they don’t have heat receptors on their tongues like as humans!
I do include coconut when available, but other then that I usually don’t do fruit, aside from a pear sometimes as Fëanor loves that so much. I do buy a mango sometimes, cut it up and freeze as a treat. I cut my veggies in small blocks, but depending on your birds you might have to run it through the food processor or leave larger pieces.
My birds also love birdie Bread, there are Many reciped for it on the forum
Last one I Made from Some seeds, a Tiny bit of flour(coconut), mashed sweet potatoes and all my left over veggies from the chop. You can do basically anything with it!
Getting them to eat healthy might be difficult, I Will come back on that when I am home!
but here is a thread on it:

I am planning to ground up flowers and use them in my next birdie Bread too.
An awesome thing to give them is sprouts! There is a great thread about it here:

My birds adore sprouts and eat them readily. They love sprouted chickpeas, mung beans, lentils and all sorts of small seeds most.
