I was probably much lower than 6.2 a lot of times. Some of the reading I did on the matter said too low a PH throttling calcium uptake took a while to show up, and when it became visible on the leaves, it had progressed pretty far.Nope. I don't ph.
Every time I tested it was within a point or so of 6.2.
If it were a ph problem I would have expected it to show from the beginning, although it did turn up early with Katrina.
The thing is, I've been giving her the same mix as my bigger tent.
They're just starting to show the same issue now, so I figure something has changed, but I don't know what.
It doesn't help that I'm moving from soil to hempy, so I have to react a lot faster when I see a problem starting.
