That’s what I always thought but saw where people were actually giving full doses and I thought that was crazy..it’s all about money ..these companies will tell u to use more so ull buy more..makes sense ..N their PPMs do seem crazy high too. I have a photo plant that I flowered out 1 month ago and i just wanted to make sure I was giving it enough ..I’m on week 9 going by schedule and I just cut off the micros as it says..I’m just nervous hoping I’m doing the right thing as this is my 1st time growing
