It's where I always start myself.........:Sharing One:
Rough Calculation Guide:
Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference
If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.
For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5
If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

Thanks again man. I must admit I haven't paid much attention to my PH lately, or the plant's to be fair (personal reasons), but I thought I had it dialed in. I do think my soil PH has dropped a bit, which is locking out some P,Ca,Mg. They are def showing faster, heavier growth under this LED, I thought I had some bleaching due to the distance of light, but no , I think I have a PH issue (again!).
