Hello. I see where you heading at.
But let's break it down for a bit.
#1 nowadays in 2022 less is actually more. Most of the brands do already include all the necessary elements, minerals and beneficials needed for the healthy growth.
Bloom boosters or any Candy King Kong mega-Cola boosters wont do shit.
GH series flora trio with CalMag is everything you actually need: micro provides the needed trace elements, CalMag for the increased Calcium & Magnesium flow and Grow&Bloom used in right ratios provides the correct NPK ratios.
#2 "Bloom Booster" thats what gets the growers attention - Does the supplement make my flowers bigger or more vivid?
…Well there is different type of Bloom boosters and the only which can actually help on the later flowering stage is PK-boosters. But again, PK boosters are just Potassium and Phosphorus which is needed in larger quantities during the flowering. So if you're using GH tripart, you could only just increase the Bloom dosage - it's the same Potassium and Phosphorus.
"Bloom booster" which does not contain any Macro nutrients are basicly BS. There might be some beneficial elements like Humic, Fulv, carb hydrates, enzymes etc. But these additives can be found in their own bottles, usually a lot cheaper and with more spesific guaranteed analysis.
#3 Mixing different brand's nutrients together usually makes more harm than good. Why? Because most of the nutes are synthetic, different brands do use different compounds and their derived forms may vary a lot, and thus that they might not dissolve together and might pack into "crystals" which can completely block out some necessary elements.
Bottom line; to get the big and healthy flowers stick to the nutes that you've used so far (GH tripart), follow GH recommendations so you get the most important part of nutrients working; fertilization ratios. GH calls for about 2-2-4 ratio for the flowering and when combined with the Ripen in later stage you'll get the about 1-3-3 ratio for the ripen phase. Put the GH ripen only in use about two-three weeks before the harvest (it basicly same as any other PK boosters).
Feeding coco plants with enzymes is a good idea, and when the roots are happy then plant will be happy.
If you're seeking for the "real ways" to get more weight on the buds then it comes down to the lighting and CO2 supplementation.
Increasing light intensity up to 900-1200ppfd and adding CO2 bag or tank will greatly result in more flower mass.
Nutrients itself only wont make your flowers bigger. And don't get me wrong - I was also a bit less than 3 years ago spending money on all kind of bloom boosters. But when you take a little deeper dive into the plants nutrition and understand what each element does then you start to realize how most of the cannabis related "boosters" are just a way to sell more.
Hope this helps at all. I get it if you're still going to look for the different Boosters and test them out - eventually you'll learn more about them.
If you need futher help for example planning a perfect "bloom boost" feeding schedule only using your current nutrient bottles, you can DM me and I can calculate ppm’s and give you a good estimates for the rest flowering phase. I've also used GH Flora/tripart for couple of rounds and I've couple solid tweaks for them!
Again, hope this helps!
