Hey brother,
I hope you don't mind me quoting and tagging
@FelipeBlu in over here to help answer your question? I truly didn't want to come across as rude or confuse the OP.
To be honest I don't run them above 1200PPM (x5 scale). I've found at that PPM it provides plenty, and I get good healthy growth still. But that doesn't really answer your question, and I think FelipeBlu might be able to answer it with a much more accurate answer then myself.
Absolutely not, appreciate it actually!
My understanding is that too much nutrients leads to nute lock-out, and the mentioned ppm translates to a value that is well above the recommended value in flower that I find for various nutrient lines that work for both hydro and soil.
For hydro, advised flowering EC is between 1.4 and 2.2
For soil, that is 1.3 and 1.7
Taking this chart:
I would think that if you are pushing an EC of 2.6, you would have to be blasting her with a small sun and supply CO2.
The interesting part is that in preflower, the recommended EC is much higher, and in the ripening phase as well. As I'm just following the label till I know what the hell I'm doing, but I did read about the nutrient lockout table where if you have too much of x, y wont be uptaken, etc. Given the not knowing what the hell I am doing, I cant really get to an answer.
Now, I have to admit, I didnt check all nutrient lines, and Im working on the assumption that EC is a generic thing that remains stable across nutrient lines in terms of min-max, with only slight deviations between the lines. This checked out between a few nutrient lines, the rest talk about ml/l only, but I could verify the EC value of that as I still have a line left from my soil adventures..
As the plant shown was showing deficiencies, and the ppm seemed rather high, I went here with my thoughts, vs supplying even more (I realize that assumes no imbalance in his recipi .. recipy .. recepi ? fuck it, mix.):
Then again, the effect that would likely show first would be nute burn?
Just trying to understand the info I found so far, and bringing that back in line with my understanding of EC
Thanks for any effort taken, dont feel obliged. I read your pH thing, some interesting parts there .. just had my own battle with that where keeping it anally at 5.8 is not a wise choice
Will read your link again at a later point, too baked to digest it properly atm
Thanks again for stopping by!
