Recharge - how often do you apply?

Yes potassium sulfate. Ill add a tiny bit to next watering. Special water because my tap is super chlorinated, 8.5ph & loaded with stuff. Last grow I battled with ph down & my plant was a yellow mess. Figured try something new out. Maybe the taps fine but these spring water plants sure look happier than last tap run.

pH down can mess shit up in soil. After time it uses up all the buffer that keeps the soil pH higher. The pH down probably fucked shit up more than anything last time if it got that bad, but who knows what's in your water. Luckily my well water isn't too bad. It's around 7.8 and 150 ppm if I remember right. But I'm glad the spring water is working better. That light seems to be working pretty good,

I use it every watering, are my plants the healthiest? No but they ain’t terrible
