The seventh week started well until I discovered some spots on the WW. It took me a few days until I was able to determine what the problem was. At first I assumed I had watered too much, which meant I didn't water for a few days. At the end of the week I was pretty sure that it was a calcium / magnesium deficiency. I then started to fix this with lime and BB Calmag fertilizer.
