As an update to what's going on with the plant that looked like it was on it's way out...it's better! I've been giving it pH adjusted water going for around 6.5 to 6.7. Also it got down to it's dry weight so I had to water. Figured I'd hammer it again!! Maybe learn something. Maybe burn it. So I gave it a half concentration shot of Schultz 10-54-10 Bloom fert. That was yesterday. Today the main fans that were yellowing and necrotic still are, but they're sticking up in the air like they're really liking the chow and new water! Plus the rest of the plant is also much more 'perky'.

I totally believe that the water pH was the problem. Now with that somewhat cured, the plant's reacting to the ferts that probably never even got used before this as they were being locked out due to the high pH. So a good lesson for you newbies and maybe even some others. Check your pH!!
