Question about Mixing Nutes!!

Hey i have a newb question,
I mixed around a little under an ounce of Pure Blend Pro with one gallon of water, i fed my plant 1 cup of this once a week, first off is that enough or should i feed every 5 days? And do i have to mix up a new gallon every time i feed? or can i just use the rest of last weeks mixture? Basically i am wondering if over a few weeks time period, will the mix become bad? This is hard for me to word out since i have just smoked a few bowls

still not answered. all info is appreciated!!

When u first start giving it nutes u usually give it a half a stength and feed it every 2 to 3 watering. Thats what i was told. I usually make a new gallon everytime i feed it. If all you need is a half a gallon of it you should try to calculate how much nutes you should put in a half a gallon at half strenth.

u can feed your plant as much as it can take, if u start seeing nute burn flush your plants and use a little less. I have left nutes in water for a week and used them again, but leaving them and adding more nutes over a long period probably isnt good.

alright i will start doing the half strength every 2-3 watering. Thank you for the help.
And for using old nute water, i heard some bacteria starts growing and eating up the nutes or some shit.

No problem. Hey wats up krypt.
