Newbie to pps pro dosing
I mixed my dry ferts according to directions on bottle from greenleaf. After waiting a night or two I dosed this morning before lights came on. When I got home my ammonia level was .5 ppm and my nitrite was .5 ppm. Is this normal. I've always heard these levels above 0 are toxic. Like I said I'm new to this. What do I need to change if anything. Water change? Less ferts. I am dosing the 2 ppm of each bottle because I have a 20 gallon long.
