Quick One indoor grow on a budget

As everyone told me, I decided to let them grow for another week. I think I'll cut them this Monday, since I'm going on a trip and won't be able to keep an eye on them for a few days. Do you think they are ready now or that I should leave them even longer, personally it is still difficult for me to see orange trichomes but as I said, it would be difficult for me to wait longer since I am going on a trip.
