I noticed that leaf color difference, too. I actually ordered those botanical leds spike producers, and I think it was your recommendation on another thread that led me to them. I checked their spectrum with my par/spectrometer when they arrived and they seem really great so I definitely think yours is getting enough and “right” light. I bet it will spike for you soon; it is clearly super healthy! I havent had mine under the botanical led spike producers (I put some different paphs under those), but under different led lights but with a similar profile and intensity, fwiw.
