You did not say what the source of your tap water is, municipal or private well
Yep, sorry 'bout that. It's municipal water. From what I've read during my research since this post, it's pretty fucking disgusting LOL. I went and bought 10 gallons of distilled last night, and am saving up for a 100gpd ro system.

The water I bought turned out to be 35PPM. I mixed my Pro Blend flowering in it last night to bring 4 gallons up to 360 PPM. The previous night I was able to flush my plants down to 600-700 depending on the plant. Total runoff after feeding was around 550. Not as high as the grow log I found, but I want to ease back into it after the previous problems I was having.

It just feels better using distilled now...better peace o' mind now that I know EXACTLY what's in it and I can control it. I know it's probably a "no shit" moment for the seasoned growers out there, it's my first grow though and I'm learning some cool shit.

Great input everyone. Thank you!
