Miracle grow bloom booster.
Like 7 bucks and it'll work just fine.
I did a side by Side comparison last year with Botanicare and MG.
The mg preformed just as well if not better. BUT I did need to add
Cal mag.
You can find a better npk from MG,
With a higher nitrogen level.

You could add coffee grounds for nitrogen in a pinch but you need
Other things at this stage

Why Not just Buy a BioBizz TRY PACK of the FleaBay, Won't cost much more than about £13 - $22 and for that You will get FishMix(better than Grow,Feeds the Soil) Bloom and Top Max only downside is they are only 250ml Bottles, but more than enough for your needs.

Peace

Good Growing

Just do something soon.
