@Dante Hi there! This looks like a cal/mag deficiency, since your leaves aren't showing any other symptoms (wavy leaves, burnt tips..), and your nutrients intakes stats are looking good, I don't think you overfed them. Another theory would a led-burn coming from a defective LED cell, this happened to me in the past, took me weeks to figure out.
In the first case, cal/mag deficiency means that your pH at the roots is too high or too low, you'll need to add extra Calcium to your waterings and carefully watch your pH & Ec/Ppm levels (maybe re-calibrate your tools). Finally, if you suspect a defective LED, you can try to look at the light with appropriate glasses, if you see a too-shiny led cell or a colorless cell or a flashy/blinky cell, you'll need to contact your panel manufacturer. Rotating your plant may help in diagnose this, because you'll notice new spots under the defective led. I'll be around, keep us up-to-date so we can help you to adjust your parameters, & happy growing! 👊
