Hi All,
I have hard water (just tested 115 PPM out of tap.) It seems like I run into the same problem at 3 weeks into flowering. My plants start to yellow and turn crazy colors. Daytime and night time temps are in the high 60's and low 70's. pH is 6.5, seems like everything is good.
I'm starting to think my hard water is causing nutrient lock out. Plant stems and leaf veins are turning a weird red. I've attached a picture, does it seem like it is a calcium def?
Please help!:icon_smile:
