It come from light bleaching (too intense) Stasis.... You got them too close to the LED....and your doing TOO good lol those are some of the prettiest plants around.
I was looking at my stuff today.. It just seems like the plants like to be further away... Of course they look brighter when your closer to the fixture, but in reality its less LEDs your getting use from, its just that your close enough for a few to really beam in on it to light it up, but when your further away your getting light/spectrum effectively from more diodes/colors... I'd rather get 75% of the light from all spectrums than 100% of light from half the spectrums.
