Every single great grower eh? Did you go and ask them all or something?
Don't twist my words.
I said - exactly - "virtually every good grower".
"virtually every" is not the same as "every". "good" is not the same as "great".
If you think even a significant percentage of growers that would qualify as being worthy of "good" (or "great", it doesn't really matter) actually recommend feeding every watering while growing in soil, prove it. Show us a significant number of such recommendations.
I base my claim - which I very clearly and specifically qualified by saying "virtually every" rather than "every" - on the following personal observations:
1. Limiting the sample to growers whom I personally consider to have knowledge and skill equal to or greater than my own.
2. Limiting the sample to growers that have experience growing in soil.
3. Limiting the sample to growers that have given advice specifically about how to feed plants grown in soil.
Under those conditions I cannot think of a SINGLE instance where someone advised feeding every watering.
Since I am not a moron, and therefore aware that things exist outside my knowledge, I chose to say "virtually every" out of acknowledgement for the possibility that someone worthy of respect made such a recommendation that I haven't seen.
Regardless, I stand by my statement that a vast majority, if not every good/great grower will recommend that people feed every other watering (or at the very least not every watering).
Two reasons for this. First, feeding every watering is much more difficult to do without screwing it up. Second, responsible and respect-worthy growers make recommendations with concern for the likelihood of a rank newbie reading and following their advice.
Someone who gives advice that actually increases the chances of a newbie screwing up their grow does not qualify as a "good grower" in my book.
