A complete well balanced plant food will do fine. Aim for a plant food high in Calcium and Magnesium.
There's many good alternatives but a stable and we'll balanced formula is Canna Coco A+B in both Coco Coir and Pro-mix(peat) based mixes. You get everything in only two parts that has enough buffers to not need any "Calmag" added on top of the formula.
On top of that added silicate at 30ppm residual Si is beneficial all the way through veg and flower. Potassium silicate, what you'll find in Pro-tekt or Agsil16H. It increases yield and quality but its negliable, more so it's good against pest by strengthening cell walls.
Humic acid/kelp mix for better chelation with better uptake and overall health. Mix the ratio 5:2 ratio of Humic acid:Kelp extract.
All the PK bloom booster do more harm than good growing in containers since you will never be able to combat the inherent low pH of MKP(mono potassium phosphate) and Cannabis need low to moderate levels of P.
NPK 3-1-4 is what's supported by science to optimally grow Cannabis. If you have that in mind many formulas make very little sense.

Good genetics and any phosphorus fertilizer.
Exactly! Some strains won't be as dense as others, regardless.

I like this stuff. https://www.kisorganics.com/products/kis-bloom-booster
It's fully organic, well balanced, designed for low heavy metal content and it contains sulphur and calcium.
