1. The plant will fix itself
2. I'd go with what the maker of the nutes advises
3. the thread title sounds like a country western song -

My woman she walked out on me
she weren't much of a gem.
I don't miss her much but now I have..
a little rot on the stem.

Oh, a little rot on the stem,
a little rot on the stem -
Use it or loose it
no way to refuse it... cause....there's...a......
little rot on the stem!
