Regarding foliar feeding:

Please read through to "the bottom line".

And I'm not a big fan of spending big bucks for a product that nature does for free. If the price tag is worth the saved week (or so) of transition, then just make sure it doesn't interfere with your nutrients, additives and soil chemistry. (it's ph, for instance...)

Any clue what's in the EarlyTurn? Have you thought of training 'em instead of adding unknown/unnecessary chemicals? (perhaps search onsite for 'low stress twisty-tie training')
