Help! Nutrient burn?

I just changed my reservoir on my 5 gallon dwc bucket yesterday and upped the nutrients. Noticed some yellow spotting today. Likely nutrient burn I imagine. What's the best thing to do from here? Is it the obvious: change water again and lower nutrients?

Tanner I'm not sure that's a nutrient burn, they usually start on the tips of the leaves not the margins.

You've got good viens on the leaves but spots starting in the margins of the lower leaves. Might be magnesium deficiency.

Just in case empty your reservoir and water with clear solution for a couple of days.
