I spent the last 30 minuts on google researching for anything related to my question but found nothing that gave me a scientific answer.

Question 2 is does rain water contain enough phosphorus to help with the flower growth or should i be also mixing in bloom food with the rain water i give my blooming mj indoor plants? Also she us more than half way through the flowering cycle.
Nooooo. You don't have chlorine, fluoride (from city water), but depending on where you are located, you might have more toxins from rain water (pollution).

Add NPK to rain water....viola`!

Is this a response to my comment about lightning fixing atmospheric nitrogen to rainwater? Are you saying that atmospheric nitrogen fixed my nitrogen is inert?

No, I'm saying whatever falls from the sky, nitrogen is basically inert.

Nitrogen gas is a very stable two-atom molecule that doesn't easily interact with other atoms or molecules. For example, although three-quarters of every breath you take consists of nitrogen, none of that is metabolized by your body. The same is true of nearly all plants -- they can't take nitrogen directly from the atmosphere. In fact, legumes that can take nitrogen from the atmosphere don't do it directly, but through a symbiotic relationship with "nitrogen-fixing" bacteria in their roots. The bacteria "breathe" in nitrogen and convert it to compounds that the roots can absorb.

Yes, yes. Everything you said is true. N2 is extremely stable, that's why only the immense energy from lightning will break those bonds.

Thanks in advance.
I do.

I'm not sure how much is fixed and besides lightning doesn't occur daily.

If you can generate 1.21 gigawatts you may get more nitrogen fixation.
