I would agree with everything Pinky said, it's probably just 'youngness' that you are tasting. Kit wines are usually not out of balance, if anything they tend to stay on the low side of things to make for earlier drinking. Young wine are usually not very pleasing, time makes a world of difference.
The more we know about your actual wines the easier it will be to answer. This is a very civil group and long posts with lots of detail are not an issue. This group has a wide range of participation so feel free to ask anything that comes up. It's not uncommon to get an answer in hours.
We can help you with the science of winemaking but over time you will see that it's more art than science. You need to balance the science by developing your personal tasting skills. It's actually a good thing that you realize you have a wine that is not exactly where you want it. The art part comes into play in predicting where it will go from here.
Question on Wine storage 23Actually it's a high horse I absolutely agree with. Would love to have an underground cellar, just really not an option in this area(t least not unless...
Wines develop in the bottle, you use the science to determine when you have the wine close enough to let it develop in peace and quiet.
