nahhh you really don't want to use that shit in your hydro. to be okay for hydro, you have to make sure that ALL nitrogen sources in the fertilizer are nitrates, and NOT nitrogen compounds, and when it doesn't say that it is for hydro, then it's most likely not. look for more specific hydro nutes, GH AN or seomething

Yeah, I use Canna Aqua for indoors but looking at going large-scale for outdoor hydro vegetables and herbs. The trouble is, the maths doesn't add up up when using £15 a litre nutes for veggies and herbs. I can see how it does for weed but tomatoes don't sell for £180 an ounce! The best I can do so far is to foliar feed using my left over stuff from res changes, watered down. There has to be a cheaper source for large-scale veggies or how would the pros do it?

The pro's make their own fertilizer blend, or they buy from outfits like Crop King: Fertilizers : Hydroponic Supplies and Greenhouse Equipment for the Professional Grower, by CropKing Inc.
Otherwise they make their own. Nutrient Formulations From Scratch. | SeedMine

I have been making my own for 2 years now and it costs about $5 per gallon to produce. The bottled stuff you get at hydroponic stores is made for hobbyists.

My recipe has:
Calcium nitrate
Potassium sulfate
Potassium nitrate
Potassium phosphate
Magnesium Sulfate
Chelated micro nutrients
All are dry compounds of differing amounts that are dissolved in hot water seperately and added to the res in a specific order. I can run 1500 PPM in the 2nd week of veg and up it to 2000 PPM for bud with great effects

I have all of the above except potassium sulfate. I also use phosphoric acid for PH-. this recipe is great for me gives me best results.
@ cues micro nutrients mix is a mixture of all the micro nutrients which are elements found in minute quantities in earth, plants need them but they are not present in water. theyr made of iron, boron, copper, lead... and what else... my mix has 7.5% chelated iron. chelated by itself is not 100% iron, but 12% iron, so I have to calculate this to know how much iron I need and how much grams of the mix I need in my recipe. it may sound complicated, but once you know what you're doing, it's really simple.

Crop king makes a 'Mirco mix' for hydroponics and it is cheap and super potent.
