Thanks MrS...I obv missed that!I believe it came in at 6.1.
It might always be a mystery since your well water didn't seem to be high on the alkalinity scale, and I haven't seen the nitrate form of N in MC to cause those kinds of issues with the substrate (or I'd probably have them with my long grows).yep, it was 6.1. Still baffled as to why the mix in the LSD plant got so high. Poor girl looks pitiful, but she’s giving what energy she can to flowers. They still look relatively ok.
Let's see if the amendment helps!
