Ok
@Dirtbag you know my stubborn ass so do a brother a solid and ban me from this thread after this post please.
So let's look at the factors that affect nutrient uptake, use and transportation in the plant.
1. Nutrient ratios
2. Light intensity
3. Light spectrum
4. Media
5. Nutrient concentration
6. Temperature air and rootzone
7. Humidity
8. Wind /air movement
9. PH
10. Plant health
11. Mobile and immobile nutrients (act much differently.
12. Nutrient sources (form of the Nutrient used like nitrate or ammonium)
13. Genetics and geographical location they are from)
14.co2 concentration
Need I go on? Now on the short list here mix and match any of the factors.
Eg. I reduce ppm beow 300 to keep a small balanced nutrient because I feel the plant still needs a proper ratio in order to uptake immobile nutrients... im not to concerned or mobile as the plant will move them as it needs.
I also reduce my temps in the last week or 2.
So when I say I find this works for me and
@Dirtbag finds that under 100ppm works best for him... which is right? (Sorry for dragging ya into my post lol but all the more reason to ban me from the thread) BOTH are correct... why because it what works for us.
Now why may we see a difference? After some thought I reduce to 300ppm but I also drop my temps reducing uptake.. possibly the same end result.
TLDR: like anything cannabis related I don't believe there is one answer and there is always a scientific answer and just because one is not given does not mean there isn't one.
When you add up all different things that affect nutrients and then take into account how they affect eachother some will see a benefit and some won't... thats my opinion. We will never find one answer that fits all because there isn't one.
@Dirtbag can you do the honors please and save me some sanity.
