It is definitely possible that the Plantex triggered the pearling if you previously had a micronutrient deficiency, but the extreme difference in PAR between the high CRI Phillips TL950 bulb and the Gro-Lux bulb you switched to seemed to illustrate the point very well. To support this argument, would you be willing to switch back to the Phillips bulbs for a few days and then back to the Gro-Lux bulbs to see if pearling discontinues and resumes?
