How to make fem autos?

Would like to produce feminized seeds from two female auto plants.
The one I want to reverse comes from actualy fem seeds.

Some ideas about timing?

When do I start spraying the indidual that will be reversed?

How much earlier should I start the plant I want to pollinate?

Peace

When it starts showing sex, rub the colloidial silver on the limbs.

It'll get burned otherwise

rub on the limbs???

Can I not just spray them.
never heard about autos being very sensitive. Always thought they were hardy little mofos.

Idk, that was the suggestion over on another thread for autos. Someone used colloidial on the leaves and everything from a young age and although it turned sexs, it was terribly burnes, sooo another guy said to rub it on the limbs only and then stressed that fact a few more times... I'll do a limb rub on mine if you want to spray yours. I'd still say wait till you see obvious sexual organs forming

In the thread I tried the organic method of extending my patience for Hermie sacks but with no luck.

I believe the burns come from to high ppm in the cs solution rather than the method used to get the cs to the plants tissue.
in the diy cs thread the OP stated a few times that he has observed burns and mutation of new growth as well as sterility of pollen related to too high ppm.

So you do experimenting with autos too?
Do you mean extending flowering time to get pollen sacks?
I heard soma using this method but I guess this only works with plants that already have a hermietrait not with hard females. I have seen females you could stress the shit out of them and they wont throw sacks on you.
the cs is a different thing and works even with those hard females.

Hopefully I dont fuck it up

Peace
