nice.. that is what i'm using right now, advanced nutrients.. all of the measurements are on the sides of the bottles.. some of them are like 2ml per litre, some are more, some less.. it all depends on which one your using..
just add the amount of nutes to your water, then check the ph with a ph meter, and adjust it down to about 6 to 7 or so.. let it sit for a couple of hours, and recheck the ph.. it may have moved a lil on you.. if so, just readjust it to the 6 to 7 range.. oh yah.. shake the water nute combo well before applying.. and btw, start off at about 1/2 or so what they have on the bottles as they always seem to run a lil on the hotter side of things.. they do this so that you'll use more nutes and need to buy more sooner.. you can even start out at like 1/4 the dose, and every week bump it up another 1/4 so that by the end of a month you are at what the bottle says you should be using.. sometimes, less is more, escpeically when it comes to nutes..
