It`s totally up 2 u but personally i wouldn`t take the risk!
u`d be far better off cutting that male down and starting over agen than holding onto it and risking any future grows that u might have planned.
Your not really going to gain anything at all by keeping that plant alive and u have quite a lot to lose!!
i`d far rather bin it now than be kicking myself in say 6 months time when u have a few nice females that u`ve spent a lot of time and money on and end up producing nothing!!!
In My Humble Opinion!!
