Was reading on IG cat was talking bout this subject, basically said and called it light bleaching, not just the albino bud effect most have experienced when putting em too close, but in effect, bleaches some trichs, more or less. Showed some pics and he claimed if you had a bigger variety of clear, amber, and cloudy and couldn't get em all to turn, and could tell in potency. Like most or some, I use cheaper LEDs so I can position em for variety of plants and I've noticed it once or twice when I'm pushing to see how close I can get lights. Just an observation
