Is gibberellic acid poisonous ?

[Giovanni Resta]

I'm starting, as an hobbist, some experiments in seed germination with 
the aid of GA-3 (gibberellic acid). Since I have two little kids 
I wonder if gibberellic acid, in the quantity that I manage,
that is about 1 mg, can be nocive if eaten or touched. 
I use all cares anyhow, but I'm always curious on substances that I use.
Thanks.
Giovanni.
