Increase feeding power

Amino acids. These are what the plant produce from the raw minerals we supply from fertilizers. Possibly one of the largest "energy" drains on a plant as it grows is having to construct its own amino acids and enzymes. These are high intensity processes within the plant that can use up alot of energy collected from photosynthesis, by providing a regular source during flower you can help the plant dramatically by providing her with the enzymes and aminos pre-made. Higher plants are special in that they can creates all 20 aminos required for life themselves but it's costly in terms of energy-efficiency. Probably single best thing you can do to increase overall efficiency.

It's environment that dictates nutrient requirements. Water cycling in the environment dictates how fast uptake occurs. Think of nutrients like the base raw materials for a construction site, throwing endless materials does not make it construct bigger or faster. The workers ability to move materials up and down the worksite efficiently is far more important than abundance of materials. Dialing in vpd alone can give more yield +20% which make it on par with full co2 supplementation. You want bigger buds? Educate yourself on how to optimize environment get it dialed in, track, ec, track ph keep them in range. Good luck in the search for biiiiig buds *burp*

You can just go with the Hesi Chart, it works and won't cause any problems in the most cases imo. if so, go with half strength. My top additives besides of the grow/bloom fertilizer are: Calmag and some PK13/14 and i like TNC BactorrS13 If you have that and still don't get nice results it's not the product, but the grower. But don't feel bad if so, we all started haha. But correct watering, pH, and environment play HUUUUUUUUUUUUUGE roles in growing a plant. more than any additives. If you just have base fertilizer but everything else is on par, the plant will look great. gooood luck!
