2020 Spring - Mephisto-stravaganza

Trying to fix the PH problems. With the nutrients at full strength the PH is usually about right. But with really low strength it seems to be too high. So I have taken it to 6.2 and now to 6.1. Trying to get to 5.9 then stabilise there. New growth looks healthier. I have changed the environment. The VPD is now right on 1.5, it had been up around 2. That should make a difference also. Will evaluate how things are going in 3-4 days and decide whether I need to try something more drastic like switching back to Canna Coco nutrients.
