Your welcome brother! I just rather someone learn from mistakes because looking back, I wish I had a lot of knowledge I have now due to all the money I flush down the toilet. I am SO glad you decided to get those ferts because you will see such a tremendous difference in your plants! To answer your question, yes, it will be fine and to back-up that statement I asked GLA about using my fridge water with its filter and they said that should be fine and even recommended me to boil it afterwards so the mixture mixes better. You don’t have to boil it though and I don’t either. But remember, your dosing chart can change and flux due to signs of deficiency that you see in your plants. If you see a plant doing something awkward, relook at your ferts and maybe up the certain fert. What I hate about it and dislike is the fact there is no right dosing mixture that works for one tank and the same for another. You will have to tweak here and there etc etc....
