Unfortunately, not every seed grows into the robust, fast growing plant everyone of us would like every time. You can continue to grow it and it WILL grow, but for one reason or another it didn't get the "grow fast" gene. Not much you can do but either waste it or grow it out, realizing if you do grow it out, it will always be behind/smallerthan the robust seeds/plants. Yummmm, I like C99 too!....shame it had to be a Cinderella99!
