The 12th day:
The concentration of GHE Flora Nova Grow is 3 ml/10l. Ph is wildly unstable, I think because of stones, vermiculite, expanded clay… During daylight hours it increases from 5.5 to 6.0. While I can not understand:worried:
The 14th day:
I understood why ph was unstable. The reason was algae. The solution temperature is 22-26, and probably somewhere light penetrates into the tank.
- Complete replacement of solution,
- 10 ml of peroxide to each tank,
- the concentration of the nutrients in new solution is 30% of the recommended.
I made the first pruning. Leaf margins of both plants began to turn yellow.
