~2 weeks is standard for plant quarantine. If they're hardy plants you can put them in water that has not had the chlorine removed to help kill any uninvited guests.
I use Flourish fertilizer and root tabs in tanks without substrate/soil and that works quite well. The combination of both is important because some plants primarily get their nutrition through roots, while others pull them out of the water column through their leaves. Also, they don't have the same nutrients in them. Root tabs have things like iron that Flourish doesn't, and vice versa.
Make sure not to confuse Flourish and Flourish Excel. Very different things
