40th day:
In - 430 ppm
Out - 300 ppm
The Nurse is getting better, BUT. The weather outside is so moist. Sometimes its 72% humidity in the growbox. The leafs started to bend up, you can see it on photos. And I don't know what to do, I guess just wait this rainy weather end.
I'm still trying to find the best amount of ppm, For me its allways hard to decide how to feed. Always too much or too small.
