Fresh made nutes vs day old?

My current watering method is a 20gallon garbage bucket with a small water pump to circulate the water. I use synthetic nutes(AN or Ludacris) and make the bucket a reservoir. I don't always use the whole bucket, so I leave it covered with the pump circulating. Sometimes a day sometimes longer to save money and not waste a batch that's already made. I notice the ph rises after a day or two, so I adjust it with some ph down. I think the plants are ok with it and they seem to grow normally. But is there anything I should be worried about? How long does a batch of synthetic nutes last with a circulating pump?

All good. My veg barrel goes for up to 3 or 4 weeks when my veg room is not full, no problems.

Any beneficial bacteria products should be added when nutrients are used. Organic nutrients should be used when mixed but with your synthetics you are good to go, just keep the circulation going.

Thanks for the reply.

I’m using these nutes, what should I add to get beneficial bacteria? Thanks.
