I don't do hydro so nute schedules is not in my scope..20-20-20 is a basic walmart./ hardware veg nute.. I used this for years but it is strong and I don't think for hydro .Nutes are on a N P K basic nute ingredients (there are micro/macro too, but for more advanced). for veg usually N will be higher and for flower P higher..but as I said I've NO hydro knowledge... I'm sure some here will help soon... luck.

thanks anyway mucka

Sounds like you put the cart before the horse big time sorry i cant help with hydro nutes .. But 20-20-20 refers to 20%nitrogen-20%phosphate-20%potassium this formula is like the starting point for basic plant food . Each plant variety will need different %s of each. Same goes for different times in a plants life i.e. Sprouts can live on water alone and its trace minerals larger vegging plants need more food and when a plant produces fruit or flowers it may need even more and different %s . Read the faq on riu it has tons of info i will help if i can though!

Hopes this helpd
