Lower buds browning

Growing under a Mars Hydro TSW 2000. Pulls 310 watts. All of the lower buds on my plants through 3 grows have been maturing way early and sometimes turning brown. It is not bud rot as I have looked at it under a dynolite with zero signs of botrytis. I have attached a pic. Has anyone else seen this under LED's? I never had this with my hps.

Honestly no never! Not used the mars but don't see a reason why it would be any different than any other white LED.
Stems look a little off, wonder if its a nutrient issue or root problem?

What's your method and why have you already cut that bud?

I grow in pro-mix and I use a mixture of Mills base nutes, Mad Farmer MOAB, and Kool Bloom dry for the final stretch. It's nothing crazy as far as nutes. I run about 2.2EC, 6.0 pH. I grow in a big facility for work and we use LED's as well and I've never seen this. Maybe I will try switching up nutes and see if I have any luck.

2.2ec is pretty heavy feeding man, I dont go over 1.4 myself.

So your saying your facility also uses LED? What do they use?

We use Fluence lights at work, I'm sure they are way better quality than my Mars but I figure LED diodes are only made by a few companies so they can't be that bad.
