@Carli_Ugelblizz, Not sure. I have 4 girls under the same conditions. Three (AK included) couldn't handle EC above 400. Showing signs of nute burn and toxicity. Maybe I have magic tap water? My town's water report's only anomaly was high (outside of compliance) manganese. Very confused about this myself. Opinions, comments or advice are welcomed.

@gottagrowsometime, Thank you, love and peace!

Full res change last night. 3 gal, EC .66, ph 6.4. Today 12PM ph 6.4, EC .68. 9PM ph 6.2, EC .71. Ph stabilized (hasn't dropped out), but EC is still rising and we're at 356ppm 1 EC. Saw some root tip dying and thought this might have been a potas or phos toxicity. If this caused the drastic ph drops and subsequent nutrient lockout. At this stage (couple weeks left); Should I bother flushing or just res change often and limp along until chop?
