Nutrient PPM's climbing by them selves in bubble buckets?

Hi all!
Have a little question on nutrients.
I'm running Bubble Buckets and have a res that is all setup for topping off the buckets when they run low. Here is the mistery: So, I have a few plants that drink up to damn near 2 gallons a day and need to be kept topped off or filled up. I started out with right around 1450-1550 ppm (somewhere in that window anyways) and after just a few days (3-4) I am checking the ppm and ph and finding that the ppm goes way high on some plants where not as high on others. I just checked yesterday and its way up at like 3000!!!! What the heck is happening??? Is it a falsity? is it just plant matter getting back into the water??? Should I ignore it and just keep topping it off??? Do I drain the entire bucket and start fresh every time?? If so, that seems like an awful amount of waste on the nuets!?

what nutrients are you using? are you using tap water?

I'm using FF Big grow, Big Bloom, Cha Ching and General hydroponics floralicious and molasses for the sweetner.

nutrients are to strong. Come down to around 1000 and see what it does.

that ppm seems high to me also,what is happening is the plants are taking in more water than nutes therefore the left over nutes are raising your ppm to dangerous levels,I would back off on the nutes a bit maybe 1200 ppm or so and top off with clean fresh ph adjusted water,and remember to keep your nutes between 60 and 70 deg. with 75 being the max with lots of bubbles and you should be fine

the water is just evaporating, less water to nuterient ratio, just mark your reservoir fill line and keep water at that level and add fresh base nutrients to bring the ppm up as it decreases. ppm fluctuation is a dangerous thing if it gets to high.

Usually when your ppm climbs the plants are drinking more water then your nute ppms. Good idea to flush for a bit then start it back up a bit lower till you find the spot where it doesn't climb. The same holds true with the opposite.

i peak at 1500 around the 4th or 5th week, definitely not the first half though. make sure you flush cause you probably nute locked them.

btw, keep it simple dude. too many nutes is a waste. DM gold base nutes, 2-5 week/ big bud, 5-7 overdrive. that's it, and i grow top notch every time.
