I PHed the water to 6.5 this week just using the molasses, which was probably a bit too much so I stopped at Day 36.
I only watered abaut 1.3 to 1.5 litres of water when the pots felt light.
Because I saw some issues which I suspected beeing PH related I also swicht my Ph of the water to 6.0.
The Blueberry cupcake grew a lot this week.
The side branching became stronger and was rapidly getting longer.
It also started to develop purple stems whish I suspect being the Blueberry genetics because none of the other plants are showing this symptoms.
