Using GA3 while blooming

Hello all, I am new to all this but i have been researching allot and am taking a botany class. In my class we are experimenting with GA3 on bush beans and have had great results. I searched online and found a water soluable GA3 that contains 20% GA3 and have read that it can be put in a res for hydro. I know that thier are very specific amounts that need to be aplied at specific times or weed plants will herm. Has anyone had any sucess with GA3?

Any info would be great, thanx
