Yes, I can see some green coming back into those fan leaves. At 37 days she is probably finishing up pre flower and about to go into full flower. You might give her one more feeding of veg nutes and then switch to flowering.
I sometimes do the same thing, pull the side branches away from the main stalk and tie them down. I don't always have room to do that indoors but it's something I almost always do with my outdoor plants. Really does help those side buds to get more light.
