Ouch! It certainly is a difficult decision whether to leave an inflo on a rooting cutting. After an experience like yours, I decided to cut all inflos off on cuttings and let it concentrate on rooting. But there are a lot of others who leave them on and they root and bloom at the same time. Go figure.

I usually leave the inflos on and make sure that I water them as if they were a cutting with no roots... I hope that you can save it... hopefully you caught it in time...
