By the way. Both pics are taken on the same day of growth for each grow. 22nd day. And the pic of the 2nd grow plant is the tallest most robust plant I have. All others are considerably smaller. So really the difference is even more pronounced between the 'no food' and the 'give 'em food' concept.

Also I'm not really trying to hammer the 'experts'. Just to suggest that what is "always right" might not be all the time. Especially if you're on top of potential 'problems'. Or at least try to be.
