In order to notice how not good it is you would have to have a control plant that you didn't chop. I guess next harvest you can try chopping just one.
Then keep the buds seperate and do a weigh in.
Mature full size fan leaves never take energy from the plant, even when they are dying. Only growing parts take energy. Mature leaves only give energy, much more than immature leaves.
Now you'll have plants trying to grow leaves to replace them when it should be putting all it's energy into producing bud and frosty trichomes.
You'll still get a good harvest, but not nearly as good as if you hadn't done that.
Wishing you the best though... Prove us wrong next time.
