I just started growing an apple from an apple that had germinated seeds inside, and at first it was thriving and growing pretty quickly but now the top part of it is drooping dowards and some of the little leaves are turning brown, the seed had gnats infested inside so I poured 1/4 cup of 3% hydrogen peroxide mixed in with a 1/2 cup of water, and now that I'm writing this I see my mistake. Anyways now the plant is starting to die, and I don't know what to do
I did pour that same mixture inside of a smaller apple that I have growing, and it seems to be doing great
