Does anyone have any clue as to what may be causing this?
Here is a summary of the attempts and results....
System: (First couple grows Ebb and Flow; (Last grow Net pots in a highly oxygenated bubbler.
Media: Rooted in rockwool cubes, hydroton.
Water: Tap water (pH at 7.0 and about 200ppm)
Water left uncovered for chlorine to evaporate.
Adjust the pH down to about 6.0.
Nutes: GH 3 part flora series.
For some reason with in a few hours the pH will spike up to almost 8.0. This is seeming to cause Zinc lock-out, as well.
Any ideas of what may be happening?
