Don't compare your grow to anybody elses, ever!
There are too many factors involved with growing that can influence growth rates, and the genetics of YOUR seed, in YOUR set up and with YOUR techniques will always be different to every other single Quick One ever grown or will be grown.
Each and every seed is an unique individual organic being and no two "Quick Ones" will ever be identical.
Besides, is week 2 eight days or 14 days??
Watering every day is not necessary, water only once the top inch or so is dry, too much water at an early age can cause a soggy substrate that then prevents good oxygen exchange between the limited roots and the air, which can slow growth.
Hope this helps,.........
