Hi there!
I would like to share some of my encountered issues;
The balsamica is doin great after all, but the tonina and wallichii not. Just like it used to be.

So, my thoughts were: increase the CO2 levels. The CO2 drop checker was now yellowish, not light green any more. I have not noticed a difference in health considering the tonina and wallichii, bu the peplis diandra and hemianthus micranthemum are beginning to get stunted at the new growth. This is probably not a direct effect of increased CO2 levels? Or can there be after all a CO2 level that is too high for the plants?
greets,
yme
