Well, I gave them 'transition' nutrients. I started just following the GH recommended feeding schedule for hydro "drain-to-waste". The plants seem to like it and it seems more defined. I have followed community GH Trio guides up til now but thought I should give the manufacturer's a chance. Flowers are starting to turn purple! I did not top or do any kind of LST. I just supercropped the main cola over to the left by bending at a 90 degree angle. It works!
