I planted my seed in the beginning of July 2017. It has been growing very well however I'm worried the growing process has slowed down. I was wondering if I should transplant it to soil now or let the stem grow to 6in-8in like all the blogs say to. It seems to have strong roots and 3 sprouts they are just very short. Also should I be changing the water regularly?

You should plant that immediately. It seems that what happened was that the terminal shoot sustained an injury at some point, and it died back. This would be the reason for the multiple shoots. Had this not happened, your plant would be at about 6-8 inches at this point. Now, the reason that the first shoot died off is likely to dirty or stagnant water. This should be changed every day, or every other day. It helps to have a little honey in the water, but you are passed that point now.
The best thing would be to go ahead and plant this, and get it going. You will want to prune back to one main stem and try to keep it that way, as these will get overbearing and hard to care for when they bush out like that.
