5.4 is on the low side. 6.1 is to high. 5.8 is what you want. If you are having wild ph fluctuations in your nutes, I would have to ask what are you using for ph adjustment and how are you mixing your nutes? A plant that is feeding normal should raise ph slightly. Are you allowing the buffers in your water to take effect before adjusting? IMO throwing more nutes/additives at a problem without proper ph is compounding the problem. Even in nature plants are not perfect, leaves yellow and die, do not form properly, ect.
i'm using the powder form of GH's pH up and down. what would you consider to be wide pH fluctuations? 5.4-5.5 to 6.1-6.2 over a week and half to two weeks...is that wild?
i mix my nutes with the distilled water, let sit for an hour or so, then i check the pH and adjust accordingly.
the reason why i have the pH low from the beginning was i thought that you wanted some swing from low to high to allow nutrients to be absorbed as different nutrients are absorbed at different pH's...is 5.4 to 6.1 too big of a swing?
