Well, you have a good point. A grow log is useful. However, what I was trying to say was, don't expect a grow log to help you now or later without learned knowledge. But you're right, we all learn from mistakes too so I see your point.
No, I'm not hard for, to, or on... sandman. Grow by numbers... that's good, I'll have to remember that. If only it were so easy.
But I suspect if people used an adequate soil, for that type of grow, and avoided adding things, they would be better off. Just saying. No grow log required then.
