Need hydro help, tangled roots!!!

I am growing in a hydro system with three plants in a 15 gallon bin. I have used this system many times with great success however this is the first time I have got a male. One of three of the plants is a male and I want to remove it but the roots are so tangled I don't know if I can ever separate them. I have read some posts where people said to just cut the male down leaving his roots in there but they will quickly rot and cause a huge problem. The plants have just entered budding and have at least a month and a half left which I think is too much time to leave those roots in. I am wondering if I should try to separate the roots as much as possible then cut the roots trying to get as much of the male roots out while trying to not cut the female roots? Obviously some male roots will be left and some female roots will be cut. Is that the best option or should I do something else?

How far along is it.. De-branch the male leaving a couple fans and it will be fine until you harvest others.

The plants were put under HPS 3 days ago and the 2 females have just started putting out hairs

So I should just cut the branches and try to pluck any balls on the main stem while trying to leave the fan leaves? Will I have to routinely check for new balls and pluck them off quickly? I am going out of town for 7 days this Saturday, will I need someone to come and check and cut out any if there are some during that time, or will they not grow large enough in one week to produce pollen?

it wont hurt anything to prune a little roots to get the male out of there.

Just cut the male at the base of the stem, you wont get root rot unless you overwater. That old root system will decompose quickly and become N.

What do you mean I wont get root rot unless I over water? Its hydro so those roots will just be sitting in a tub of water with all the roots from the two females.
