My trees are all inside since almost three weeks now. Lots of extra light, because of plant density also humid. I would say almost tropical. I see a lot of new growth and flower buds forming. Lemon flush is not purple like I would see in summer. Is it because of the artificial light? Or nutritional?
Here is my Buddhas Hand as an example
My Meyer, flowers are all white and only some of them a very slight hint of purple
Do I need different light to get purple? Or does it matter at all?
