Got it....
This is a hobby where it is all too easy to throw money at it and hope for amazing results. If you just know how to observe your plants, and listen to them, you can do a lot of stuff "wrong" along the way, according to the self proclaimed "experts", and knock it out of the park. But don't ever be afraid to try new things and experiment. It's a HOBBY, it should be FUN. I've ruined a lot of hobbies by taking it way too seriously. One of my hobbies is now my job. Growing isn't my job. It is my fun, my head clearing time.
According to many, I: feed too high a PPM, I shouldn't use the coco/soil mix I do, I shouldn't use CO2 bags, my PPFD is too high, I should LST more, I shouldn't top my plants. But...I usually get great results. Not a brag either. I just love observing my plants, seeing what they will do and having FUN. Like everything else in life, the answers are usually right there in front of you. You just have to figure out how to hear them. And always want to learn. A day without learning something, is a day wasted.
