From what I understand, the key is the concentration of GA in the solution. (which, I didn't fully understand, and burned the ladies, lol)

Like I said, I used Mega Gro, and their website has some helpful GA info. GA Growing Tips
After the growing tips, it lists the different application rates and 'special' concentrations. (page 6)

I don't know which product you did get, but perhaps their website would have some product-specific info along the same lines. But start out with lower concentrations, either way.

Come to think of it, that's one of the reasons for my frustration with the stuff. I wanted it to save a strain but had no experience with GA. Was running out of time, and was getting desperate. I went with the higher dilution rates, and paid the price of panicked ignorance. Once I burned the branches I sprayed it on, and I found aspirin worked, I never used it for femming again.
I have used it on occation for tough to crack seeds though.

Coffee's ready, and it's Amber's turn on the computer. BBL.
