No, I got that.
I'm saying that tap water is better. Ignore chlorination stories, especially for your first grow.
Unless your local water supply is really f-cked up pH wise, use that ... it has trace elements and minerals that your plants need. Those might be in small quantities, but they are important 'catalysts' which facilitate other nutrient processes.
But for now, as a catch up boost, look into some kelp. Give your plants a water + kelp feed, and a half-strength foliar spray. Sea life has all those trace elements from land water runoff into the oceans.
Kelp is a cannabis tonic. Always good for the ladies, and won't make any existing problem worse. It's kind and organic, the plants will take what they need from it.
