So I'm just about to start my first grow. It'll be in a DWC Scrog "Super Bucket". A few days ago I filled up my 20-gallon res to let the chlorine evaporate. Today I balanced the PH and it's ready to drop the clones in, but I haven't added nutes yet. When I'm ready to add the nutes, can I mix say 1 gallon of water with enough nutes for a 20 gallon batch, and dump that in my already full res? I can't think of any problems with this method, but I really don't wanna mess up so early into my first try.
or lets say its 2 tsps per gal. thats what FFGB is. so you 1/4 it so. 1/2 tsps per gal. so 1/2 times 20 = 10. so fill up your tank and add 20 tsps. or find how many cups that is. just makes it easier in my opinion. because we know that way works.
