Unnatural light spectrum unnatural nute usage. Intensity would exacerbate any imbalances. Plants evolved to use the suns spectrum and can probably effectively use more light with a better CRI. But at the same time can only EFFICIENTLY use so much light. Studies show cannabis grows better at 1500umol or less. Having lights too close can easily exceed 1500umol. DLI must be considered too, in nature it ain't high noon all day long.....Photon colors hit photo system 1 and 2 and chlorophyll a and b differently which changes the cycle speed and the secondary metabolite usage. Has nothing to do with intensity.. in more intense light you use less nutes to prevent stoma gas off burns. Different light color makes a plant use nutes different.
