Nutrient burn or deficiency?

Hello All. Thanks for viewing my post.

The problem that you see in the images is pretty widespread in my greenhouse. The only areas *not* affected are new growth.

I'm growing in 20g fabric pots, watering every ~3 days, and using GH trio (+Calmag). For the past few weeks I've been feeding at 100% ( ~700ppm ), and then feed at 50% ( ~400ppm ). My water is always ph balanced to 6.2ish, and I'm using 100% RO water. My plants seem healthy overall. That said, this is my first grow so I can't say for sure.

I really appreciate any input. Thank-you in advance!

*Plants are a few weeks into flowering.
