The Lifecircle of this plant Ends soon. The Plant knows it and autumncolors appear. Dont worry About it and concentrate in the Flower ( just like the Plant does it)
To do a intermitting flush is no Problem for the Plant,,, if you continue feeding after.
Ist no Problem for the plant to be harvested partially.
Ist just close to the end and the Plant knows that…. she gives all Energy into the Flowers now.
Happy harvesting
