Lower Leaf Issue

I’m currently in week 4 of flower.. Everything looks great for the most part, but I’ve noticed that some of the lower leaves are looking like this. I’m using Botanicare Bloom, Hydroplex and Bud Candy with Calmag and Silica Blast. I don’t feel like I was overfeeding, because my nute mix was never higher than 700-900, with an EC of 1.2. It’s weird, because the top of the plant looks great. Any ideas on what this could be? Last pic shows how the rest of the plant is looking great. Should I be concerned? Thank you!!

I'm thinking Nut Burn.

Might cut back it will take awhile but should strahten out. Oh you might want to flush.

Yeah, cut back on the nitrogen, and don't flush. The damage doesn't look too awful.

Lack of light penetration to lowers creating a P def. Just ignore it, pull the leaves as they die or clean up your lowers. I see no signs of nutrient burn.
