I was reading “Complete Guide for Growing Plants Hydroponically, J. Benton Jones, Jr.” and read this “Filtering the nutrient solution is not a common practice, nor is it recommended in most of the literature on hydroponics. The only exception would be water dispensed through a drip irrigation system”
After recently installing a RO system with UV filters i’ve been adjusting my nutrient formula (Current Culture Nutrients, Ebb&Flow) to adjust for deficiencies from the RO.
I am still adjusting quite a few controls since I just moved into my new building, but I started thinking that the sediment filter I installed on my Ebb&Flow might have some effect? My daily ppm’s are pretty consistent.
I haven’t heard of any reasons why you wouldn’t filter Nutrient Water before, and the reading from J. Benton didn’t elaborate any further.
Does anyone know of an adverse affect from these filters on nutrient water?
I haven’t been able to finely tune my nutrient formula enough to account for not using well water.
I am using Current Cultures nutrient line with their CoCo Cal, But at their recommended dosage I still seem to experience slow growth, and yellowing of the lower leaves in veg (Leaves are not hidden or yellowing from a loss of light)
In Ed Rosenthal’s Growers handbook he states the water must be brought up to 150ppm. I seem to be around 80ppm using the general recommendations from Current Culture.
Anyone else have a baseline ppm for Ca-Mg when using 0ppm RO water?
I really appreciate any feedback, These forums are amazing
