Organic nutrients are generally discouraged with hydroponics.. I know if you are fairly competent with organics you can use organics in hydro but it's not a "common" practice thing. Organics do much better in soil.. Chemical nutrients tend to be a lot better for hydroponics and coco growing. Organic products tend to create issues of bacteria and all sorts of nasty things.. Even tho companies say their product is compatible with hydro.. It's a lot better to not "believe" bottles. I believe the General Hydroponics Organic line is being discontinued and they are changing over and rebranding a new line of organic stuff.. On a side node Organic nutrients also have a very short shelf life.. So if your bottles were purchased from a local hydro store or even online. There is a strong chance that the bottles are old and/or past due.
