Whatever was picked from these shall be redeemed - כל הנלקט מזה יהא מחולל
When the צנועין said כל הנלקט מחולל, it was in the morning and they said that whatever will be picked today will be redeemed by the set aside money, when the fruit will be picked. They were not מחלל the entire כרם initially either because they wanted to bring the fruit to ירושלים, or the חילול would not include future growth.
Everything which the poor gathered today should be Hefker - כל שלקטו עניים היום יהא הפקר
The owners are מפקיר the לקט in order to prevent the עניים from transgressing the איסור of בלתי מעושר. This is effective only if the owners were not מייאש. The יאוש which is a result of אבידה exempts it from מעשר, but not the יאוש מחמת גזילה.
