That's impressive to be so far into flowering without nutrients. I'd get a good bloom fertilizer in your watering regimen, which will help those flowers fill out more. Your choices are pretty much unlimited when it comes to fertilizers, just search around these forums for the bloom ferts that are commonly used by growers. (The 'Search' feature up top is a blessing.) And any time you use purified water over tap water, you MUST add Calmag to it, or you'll almost always end up with deficiencies. What it does is replaces the important elements that have been removed by the water purification, like Calcium, Magnesium, Iron, and more.

Is the pH of your tap water stable enough to use for the time being? If so, I'd start watering with it until you can pick up a bottle of Calmag+.
