Definitely techniques play a role, environment, air movement, co2 Ppm, lights . But when it comes to feed, the plant wants certain npk during diff times of flower. Key is finding out when. Let’s take pk boost for example. Some ppl use it around week 4-6 I think it’s way too late to use it then: But that’s just how I see the plants needs. I can be super wrong but I’ve yet to see my buds throw white pistols late in flower. My buds normally all finish around same time.. I like to think it’s how I’m feeding them? I can be wrong but it’s been working for me.
or how bout this hey your buds look the same? Maybe it’s the way I’m feeding ??
