Plant problemz maybe temps to high or nutrients too strong?

Troubleshooting Stress

Could be a temperature problem. Moved to a 4x2 box a few days ago and the temps got high. Took her out and I am leaving inside the house but not in a box. The discoloration moves up the plant. I did change my feed from general all purpose fertilizer to tomato bloom at the same time this went into the box. It’s been flowering about 3 weeks.
