Thanks Latewood that helps if you are right. I guess it's just optimum nutrient availability and not exactly "nutrient availability" like it says. It shows exactly none for P below 5.8, so to me thats said none was available below 5.8. Little misleading or confusing or something. Maybe it should be a gradual bar on there instead of one solid one ending at 5.8.
Opie Yutts Reviewed by Opie Yutts on . Please help me understand the FAQ charts So, if I understand the FAQ chart correctly, I have not been letting my plants get any Phosphorus or Manganes because my PH is below 5.8. How is this possible? Wouldn't my plants be dead or extremely sleepy? I thought they needed that stuff. Am I reading the chart wrong? Also, I thought I remember posts about people keeping their PPM below 3000, but the charts say not to go above 1400. Is this what you guys do? Will they fry above 1400? Oh yeah, I'm growing in hydro.
