When to spray femi auto plant.

[GoeRilla]

Hi.
I have a 2 week old femi plant I want to reverse with STS for making seeds.
How soon can I do that without risking the life of the plant.
Sorry if this has been asked before.
Edit: The plant is 2 weeks, wrote 1 week first.

Rilla.

Start about a week before flower (assuming sts is similar to cs)
Sure a sts user will be along soon enough.

Spray as soon as the plant shows sex in preflower
