I think you didn't went too far, but you are close to it. I'll did a massive defoliation on one of my last grows, much more than you. The results were that colas didn't join from abobe to top, and buds were not densde at all, but the product was still awesome and production was not terrible at all, but was no good. You can check the video of the defoliation i mean in this diary:

Week 9, video numbered as 2, and also check the harvest page. After check that you will be not worried ;)
All the best!!!, Green Love! 💚💚💚
