Fluctuating PH?

Does maintaining a constant PH through veg and flower allow plants to uptake all the available nutrients?

Maintaining a constant pH will drive you crazy and you will never be able to go for munchies. Now what I do is set a range for my pH and let it ride.

I'm in water so I set my range from 5.4 to 6.1 as long as it's in the range I do nothing.

Water and soil are not the same. I keep my soil range at 6.2 to 6.8.

Woods brings out the same old chart, year after year. And you know what? Unlike your father's desktop, it still works beautifully!

The amazing thing about this for me personally is in the interplay between physics, chemistry, biology, plant husbandry, construction, hvac, etc etc etc... it's not just the knowledge that fascinates, it's how all these inputs work together.

For instance, run 1.8ec in your rdwc in 40% rh, and you'll burn the living shit out of your plants. But at 80% rh, things work swimmingly! Go figure; keep following the 'why' about how this trick works and there is no telling where you'll end up!

letting it drift a bit like woods said is better then constant ph imo.it lets the plants get at more of everything.i try to keep hydro between 5.2 & 6.2 and soil between 5.8 & 6.8 seems to work good for me

That pH 'swing' will tell you some important things about how your plants are taking up their nutrients. If your pH lies to slowly swing upwards, your nutrient solution is close to perfect or perhaps a touch weak- not bad to keep a margin for error if your environmental conditions change a lot (eg. open room style). If your pH stays stable that's great- and if it creeps down, that's an indication the your nutrient strength might be a bit high for their liking.

Thanks for all the great answers! I have never grown in hydro so this is all new to me.
