trying to dial in ferts
So now that I have my c02 all set according to the ph/kh chart, DC, and the fish, I have to rule this out (on 2hrs before lights on and 1hr off before lights off) . My lights are a ray 2 and a fugeray on top of a 24" tall tank thats only 13" wide on for 8hrs. I'm still showing signs of deficiency, brown edges on lower leaves but nice new growth on top, sunset hygro has some twisted pale new growth. It's the brown edges/dying bottom leaves that really irritate me.
I'm dosing 3x a week EI for a 60 gallon. It's loaded with all stems. I calibrated my api test kit and find i have 30-40ppm of nitrate in the middle of the week and 2-5ppm of phosphate.
Also contacted my village for a water report for Ca and Mg this is what I got-Mineral hardness (calcium) is not regulated by the Illinois EPA because it is not considered a harmful substance. The level we find in the Longford area averages about 18 grains/gallon, or 308 parts per million. Magnesium was not detected in any samples.
1. Should I lower/stop my N and P dosing and just dose K and traces?
2. With the water report do I dose extra Mg?
3. Any idea why I'm still getting brown edges on plants?
Any help would be appreciated.
