Some of the things people say lol...
Cannabis wants/needs lots of elements for healthy growth and to bring it to it's fullest potential. You want to impact your yields and resin production? Don't use a P/K boost lol. And don't use broad spectrum lighting with UV included either.
You're feeding chemicals to a media, and your plants are eating those chemicals. They are all the same chemicals - the way you feed them may be different, they are all the same chemicals, and uptaken in the same way, and the plant doesn't care how you feed it. They will perform better if you feed soluble readily available fertilizers in an optimal Ph range, and as well keep your root zone in an optimal range...
In other words, it's all about your environment. You can feed however you like, you can obtain optimal performance in soil or hydro, or fuck em both up equally as well. If you lack a nutrient the plant wants, especially at a particular time it wants/need it, then you might impact your quality/yield. The biggest limiting factors in soil or with organic cannabis is lack of calcium and growers thinking they can "just let the soil do all the work"... You are just giving a plant slow release nutes, often times too slow for cannabis and what it needs and wants, especially in blooming. If someone doesn't know this or can't accept this, well you can't help flat earther's either. I don't have time to type out books worth of science lectures that are going to be dismissed with hippie drivel anyway. And boy oh boy if you want hippie drivel just read threads on icmag!
Use a pk boost. Whats the best? There is no best (well, there are some that are definitely better than others, and some I would avoid) - they all work, they are all good, this is why they are around, and they are companies, and exist, and people buy their products. Its not because it is snake oil or they are just robbing you, companies offer a service/product sure you could maybe do all on your own for cheaper maybe maybe, but also more time and effort for you too.. I go to dunks because it's not only what I want, and they make what I want, it's also convenient. Sure I could pay pennies for what costs me 3 bucks in a cup, but I don't got time for that shit! Oh I'm gonna buy all the ingredients, spend all this time doing it myself. K so I just spent 100 bucks on equipment and ingredients and gotta do it all myself FUCK I just coulda got a 3 dollar coffee made for me in 2 minutes.
Theres a reason why you buy pre-done bottled nutes specifically formulated for cannabis with specific nutrient schedules all done up to reflect what cannabis wants and needs at specific times. Thats why you add a pk booster from week ~4-6, because we figured out it needs it and does best with it. Doesn't matter if you are using high P guano or Koolbloom or Fire, all that does matter is you use something. But if you use (solid) organic amendments, those are all slow release, and you need to really have experience and know what you are doing to have good results - and for a cultivated blooming plant like cannabis that has nutrient requirements off the charts comparable to many other agro food crops like corn, you want to feed those bitches, and often times slow release organic nutes don't cut the mustard. If you're going to argue out of any brand of cal mag not being necessary, especially using some kind of other supplement even like liquid bone meal or the like, over calcium nitrate, idk I can't even have this conversation with someone lol
Or you know fuck me whatever its all bullshit
