I just checked up on my double grape plant. I had forgot she was out there for 2 WEEKS!!!!!! while I was out of town and busy as hell with spring.
But somehow she found a way. The hydro rez was way way low, but due to my low PPM and high end nutes it held its it's pH stable and she is still healthy, and showing female too!
I had a bit of luck, and lots of planning to allow this good news.
