Damn... Even if the guy is full of shit and has no clue what he's doing does it really do any good to harass the shit out of him? Wanna my guess would be that it means the first week of veg, once it's fully germinated or rooted (if it's a clone). Any nutrient feeding schedule probably be reduced at least 1/3 - 1/4 for the first feeding. If your plants need more give it more... If you normally don't give your plants nutes until two weeks and that works for you stick with it man.
