I mess it all up

I few weeks back (about a mont ) I had some PM (on my one and only ) plant , and I heard that hydrogen peroxide works,
so I spray H2O2 on the plant and now the pistils are brown like burn most of them.
(My plant was on flora stage when I spayed with H2O2)
I only sprayed 2 times in two days.
And i sprayed them while the lights were on
Can the pistil grow back again ??
Is the plant gonna stop growing??
What should I do
Should I worry , I’m really concerned
BTW English is not my first language

Looks OK to me

No way to take it back.. Onward I say !

Your English is fine. Promise. Fresh pistils might appear. Might not. Doesn't matter. Keep going. Don't spray anything on flowering plants if possible.

All you can do is learn and move on, we all mess up from time to time, despite out best efforts.

Looks fine. let them finish, like said before we all do it lol! happy growing ahead
