@erichbubig I have two strips of blue and red LED lights on each shelf in a big West facing window. The shelf he’s on also has a regular red and blue LED light. I’m in Western New York, so I am not getting much sun right now. I have a few places that have Southern exposure instead of lights. I just moved him there to see if it helps!
Well I would suggest that since it’s a west facing window and it’s not receiving normal amounts of light that you find a bulb that is between 5000-6500 lumens in order to better simulate normal sunlight as well as prevent etiolation. Although two colored bulbs will provide benefit as you can see with your flowers blooming, they will still extend to try and get more light.
