Like I said in my original post, the run off was something ridiculous like 8.5 ph. I'm pretty damned sure that was ph lock out. They are in a mixture of perlite and manure which I flushed all the nutes out of and the necrotic spots weren't just on the tips of the leaves, they were spotty all over the leaf along with a slight yellowing of the leaf...looked EXACTLY like the symptoms of the Ph lockout I had experienced on my first grow.

Still have NO IDEA what caused the PH to shoot up that high though.
