Help with figuring out this problem

It's the goto fix all apparently. One reason is that many nutrient lines leave it out so they can sell you another bottle of stuff. I grow in coco and I never use calmag. I never used it in flood and drain hydro either. But when your nutrients have enough cal and mag in it already it isn't necessary. Another thing that seems to be the goto these days is checking runoff pH in soil. It doesn't tell what the pH actually is but there are some youtube video's of some dude doing it and then flooding his medium with pH'd water until the runoff is where they want it. People would be better off if they didn't follow the advice of some dude with crappy looking burned up plants on youtube. Ok, got off topic but the runoff pH is just another example of the herd mentality.

huh, ok, Im hearing you man, Im not being a know it all, im not an expert. I just know, since i HAVENT been adding calmag from start to finish in some fashion, my plants go to hell 3 weeks into flower. since i started to add calmag, or mag, they got better. I actually saved my current from death, just by adding just calmag, and now she is full steam ahead. My problem i think is I use cocoloco, and i start giving them nutes to early, and was giving them to many at the time till i learned the PPM to watts ratio. Now i wait till the most bottom leaves turn pale, then add ppms to the water. Im doing a very strict "figure it out" thing now, lol..

Im just saying, since ive added calmag, and then my flowering plant just mag, it has really changed the growth almost instantly. Stopped the leaf symptoms in their tracks. If any constellation, all my strains have some sort of OG in them,

Thanks for the lesson man, writing it down in my book after i finish this.
