Top of the plant touching light (burn problem)

My 8 weeks old WW plant became very tall.I have limited space so i tied the plant to right then to left to make it far away from the light because it was so close.Now it is almost 5 fingers away from the light and top leafs started to burn&dry.I am planning to harvest next week and there is nothing i can do to solve the problem.What do u think will happen?

8 weeks into flowering or growing for 8 weeks, if you've been growing for 8 weeks top the plant at the second node if your 8 weeks into flowering just try and use the system your using of bending to create more space, what light you using?

Flowering 8 weeks under 250w HPS light.I will cut it in a week.top is pretty f***ked up what should I do
