Effects of Gibberellic acid on garden plants

Barely a week ago, I decided to make use of my 20 grams of gibberellic acid, and mixed up what hopefully was a 200 ppm solution. GA increases plant internode lengths, and is commonly used to roughly double commercial grape and sugarcane yields.

To test the solution, I sprayed it on one Ichiban Eggplant, one wide pot of five Spicy Globe Basil plants, one Mentha spicata plant, and one sorrel plant. Here are the results, one week in:



It appears that only one or two basil plants have begun to show any signs of increasing height. The plants were growing vigorously as it is.



Here is where the difference is most noticeable, and especially in the picture below. The eggplant has doubled in height and growth in one week, especially in the top half. 


Notice how tall the plant has gotten. It's not necessarily spindly (though it definitely could use fertilizer),  it is simply being stretched, so that normal growth becomes elongated, like taffy.


Most of the top four inches of growth on the stalks of this mint occurred over the week. 


Updates will continue, especially as the eggplant begins to produce on very elongated stems.
