Tiger Bloom in hydro

Does anyone have experience using tiger bloom in a hydro setup. My ph will drop rapidly from 6.2 to 5.3 in a couple of hours. I have drained and cleaned the tote and change my nutes weekly the problem still persists. I'm running through a 32oz bottle of ph up in month only using 8-9 gal of water in the rez. I did a flush for 24hr with sledgehammer and the ph held stable the whole time drained and added the nutes then the problem came back.

Wow there's no one that used Fox Farm Tiger Bloom with a hydro setup here anyone with a idea?

i use fox farm and i have never had this problem , my ph swings from 5.5 to 6.0

it sounds to me like your ph is perfect it should swing from 5.5-6.0 5.8 is best but when the ph slowely drifts like that the plant then has the ability to take up all nutrients in the water.

plus tiger bloom and grow big are chemicals the big bloom is the organic stuff which in organics when the microbes eat the organic material it can cause your ph to swing also
