RO Water VS. LA Tap Water

[medstudent]

This thread will cover my test of RO water from the machine VS LA tap Water. Im testing on two vegged OG SFVs. Im doing this in my smaller closet grow, both plants having grown up the same, with RO water, 400W hanging light, fans, smart pots, soil, CAPs bennys...
Im 4 week into flower switching one of the two plants from RO water with nutes, to LA tap water with nutes. The other plant I will fininsh with RO. I will report on quality, vibrancy, and yield.

Also this must naturaly be a first run of RO Water VS LA tap Water test, since I should have given one plant RO and the other Tap through veg as well as flower. I will likely do a second run like that.

My small grow closet, with netting, the plant on the right is the one getting RO water, the one on the left is getting the LA tap. Just some photos taken after the first tap watering, so we can fallow the divergences, if any...

Um. What is the ppm/pH reading of the tap water?

How much does it fluctuate day-to-day/week-to-week.

You should chart these reading for a side-by-side like this.

And check with your municipal water provider you might be able to get a fairly detailed source analysis from them.
