I don't flush anymore, 2 weeks prior to harvest. But I also don't feed with complex multi nutrient brand recepie. "Keep it simple stupid" is my preference. I tried flushing because like you, I read everywhere to just do it, but after researching more into and trying a no flush grow, in never went back! Think about it: 2 weeks is ~25% of your flowering time, and at this crucial moment when they finish you completely deny them food?!? Don't be afraid to get informed but also question what you read or at least keep an open mind to other ways and decide what's best for you. Whether it's about flushing, light cycles, nutrients, etc....
Read up on drying/curing your harvest properly, if you haven't already. it makes a huge difference in the quality of the smoke and is all too often disregarded as "simple, easy and straight forward" by first timers and you end up going to fast or over drying it. I know I did!
Cheers, and enjoy your first homegrown smoke! It's the best no matter how "bad" it seems
