Deficiency or nute burn?

[fwesH]

Hi guys, would greatly appreciate it if you could diagnose my poor baby.

I'm inclined to think that this is a deficiency due to PH lockout. I have been feeding her, but I discovered yesterday that I have been using water below 6.0 :S (don't ask why).

The problem started on the upper leaves. The new growth has been less problematic (as a result, only the middle leaves are the worst affected), but the end tips are still turning brown.

Anyways what does this look like to you? This is a super silver haze growing under CFLs (2 inches away).

Nethertheless, I've flushed her with 3 parts water to 1 soil yesterday (ph 6ish)

If you have had pH issues, after taking care of that problem, I would wait it out. pH issues will cause nutrient lockout, so trying to fix nutrient problems, will just cause other problems.

Just fix the pH and everything should come back fine.

thats p-mag def from lockout. kelp-Flush like 3 gallons ro water through her then add veg-nutes at 1 tsp per gallon in the last gallon.

Then let her dry out.
