Fatih,

I am not a proffessional grower by any means. But I see you are giving yourself stress over this so I will give my OPINION.

The 6 inch deep pot is too shallow. The tap root on the oak will hit bottom very soon. Use tall skinny pots. By that I mean you need deep pots, not large diameter. Stop spraying the trees and water them by pouring water directly on the soil. When you water, add enough water to water deeply. The pots should have a drain hole in the bottom or be permeable so the excess water can escape. Water only when you cannot reach moist soil with your finger stuck in the soil. This could be a few days or once a day, depending on your soil's ability to retain water in your environment.
