Once we have that information, we can proceed from there. You may find that you have to aerate your water for a period of time before you can use it so that chlorine or other evaporative chemicals can get out of it. Then you would decide how much you want to feed them and mix that into the solution. At that point you would check the ppm of the solution and then check the pH before doing anything else. Some nutrients require that you aerate the solution for a period of time before doing any adjustments to the pH in order to allow buffers in the solution to work themselves in. Then you would do a pH adjustment, allow it to sit for a period of time, and then check again and possibly readjust.
This seems quite a bit tedious to do but you only have to do this until you learn what the nutrient brand, local water, and buffers are going to do each time. After you have done it a few times, it will become way easier and repetitive to do a water/solution set up. And doing periodic adjustments will also get easier as well.
I highly recommend that you get a notebook or something to keep notes on everything. That way you can go back and see changes that you made. And don't do it stoned :stoned:
