Deficiency or Toxicity?

First time growing any Mephisto Genetics here and in the last 3-4 days I’ve been noticing a change in my leaves. The photo is a color accurate shot of what is happening: orange/rust colored spotting, curling tips and yellowing starting from the edges and working in. Here’s the info on the strain:

Mephisto’s Wedding X MBAP 68 days from sprout Growing in a VGrow 5 gallon pot Drip feed with wicking base Running the following nutes:

Drip Hydro line- Power SI Bloom 1ml/gal CalMag 1ml/gal Base A 8ml/gal Base B 10ml/gal

FloraFlex line- Bulky B 1.75g/gal

Impello Biosciences line- Lumina 4ml/gal Continuum 0.5ml/gal Nero 0.5ml/gal

Is this something fixable or is this just how Meph phenos go? I’ve seen similar things in some of Jimbo’s videos, so maybe it’s just the strain nearing the end of its life cycle?
