Lol sorry folks, busy home life
I've got her on clean water, I reckon you're right @mellowed and it's a lockout. There's yellowing around the new leaves now which looks like phosphorous
My background EC is 0.6
I've got 5 others in DWC buckets all on 1.0 EC and doing fine. This northern lights was on 1.0 when it started showing this deficiency so I figured it was just hungry and increased the EC, but didn't work
