Keep good notes. I've got a notebook that I keep track of everything in, couldn't imagine growing without it with my memory!

Wouldn't grow without it.
2. Philosophy.
Quit trying to grow the plant. It has a genetic predisposition. It can only respond to the environmental stimuli present. Learn to fine tune your only two controlling factors....environment around the root zone and the environment surrounding the foliage. Learn to control variables in those areas...and the plant will respond with the best genetic expressions it contains.

This doesn't actually have to do with the actual growing portion.
Get your op setup properly the first time. Finding out you have temp/humidity/electrical issues mid grow sucks and is a PITA to fix.
Also something I learned recently, let your plants finish. Most harvest too early
