Deficiency or nute burn?


New Member
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)
