Yellowing Fan Leaves Week 6 of Flower - N deficiency? Fix or let her be

[SpanishTrampoline]

Day 105 since seedling
Day 38 of flower (week 6) - unknown strain. Peatmoss+Vermiculite 50-50%
Fed veg nutes until a week after 12-12 and switched to flowering nutes since.
600 W LED only till about a week ago and now supplemented with 240W CFLs on the side.
Ph hovers between 6-6.8
Lights about a 16 inches(LED) and 4 inches (CFL away)

Im beginning to see a bunch of yellowing fan leaves, the buds themselves seem fine. Started at the middle/bottom and at the edges of the leaves which seems like would be N deficiency. Do I do anything or, is it normal for this stage of the plant?

Thats not N def. if anything thats magnesium def, and nute burn from over feeding and or ph lock out.

Thank you for the response. My ph seems fine and have been feeding Mg, Ill flush for the next couple of waterings and see if that helps with any potential nute lockout/ph issues. And after that up my Mg feed.

Thank you

Your watering PH maybe but your ROOT ZONE ph is not.

Check your run off.
