No, no, not what I said, its just that I've seen OKish weed grown without pH control
The problems I listed tend to show greater, more harmful effects faster than pH a bit off.
If you knew the alkalinity of your water, most agricultural fertilizers will tell you exactly how much they will acidify or basify the soil per quantity of weight.
Farmers don't have time or money to keep applying amendments and shit. But with those two peices of info they can exactly plan what to add to their mix to settle the pH where needed.
All fertilizers are not the same, older types, will push your pH down, nitrate-based ones will push it up. Chelates, however, are not so dependent on pH to get into your plants.
I always try and teach people, learn how to make your chelates and the ratios.
Calsium with folic and humic acid, or kelp and amino acids for example. This can achieve thousand to ten thousand times the amount of nutrient uptake.
