This is the last week of veg because I can already see the first pistils forming. During the 4th week, I again watered my plant only once - with 750 ml of water plus a bit of Fish-Mix and Top-Max.
I only visited my secret garden at sunrise, and my Gorilla Blue didn't look perky. I suspected overwatering because the surface of the soil was always moist. But maybe the leaves were drooping simply because the sun wasn't yet up. I decided to make the next scheduled visit at the end of the day, but she hardly looked better and was very lopsided because of the wind.
I decided to take a longer break between the waterings the next time. We'll see how it goes. The wether has been sunny throughout, with clear and cool nights.
