Pretty sure the experts around here will ask for more info. Type of system, water source and quality, brand of nutes, chiller, sterile?

Normal water? Is it tap, city, RO water?
Sorry, but i am not familiar with Advanced Nutes so i can't speculate.
A chiller helps keep the water at a certain temp. Those of us without a chiller run a sterile rez to keep nasty stuff out of our system.

More infos are needed, such as growing phase, watering daily amount, kind of fluctuation (e.g. from 6 to 6.3 in 24h)... Also, some pictures would be useful.
As primary advice, I can tell you to check your EC first. If it is stable a normal raise of pH is normal. If it's falling or raising you should face this problem first.

Well i'm a beginner on Hydroponia. I don't have a chiller. Temperature is about 26 to 28ªcelsius, humidity about 50 to 60 . the room is 1,10mx 1,60 x 2,50m . The flutuation is much bigger 5,5 to 7,5 . I go check and see how it it is.

Tap water should rise in ph for a day or 2 after coming out of the tap.
Do you not have ph down?
So when I make a res I ph under 6. Next day it is 6.5. Then I lower it again to what I want and it normally stays around that area.
Are you using the PH perfect advanced nutrients?
Those water temps are hi. You are going to have some issues with bacteria.

Well, you should raise a little the Humidity, but beside these infos, you should also tell us:
How is your EC? Is it fluctuating or stable? Which is the week and the phase of grow (veg or bloom?). Which is the strain (autoflower or feminized)?
5,5 to 7,5 in one day is too much ! Do she is showing other symptoms (e.g. on the leaves)?
the EC is lower like 300 ppm is in veg with 3 or 5 days
Seems yes, but i will do one calibration just to make sure. The Ec is very low like 300 ppm. My plants are auto critical and ak47 2 of each, they have about 3, 4 days . Ive been checking the Ph and seems to be more stable, lets see tomorrow morning how is.

I have to add ph down the day I mix a res. And the day after. And then when I add more water to my res. I add a little more ph down but don't need to check the 2nd day.
300 ec is fine. That is what my tap water is. I dont use any nutes for 2 weeks.
Well. I put it at 400. So only 100 ec food

Are you using tap water or RO water? If tap is it city tap or we’ll water? I ask because it makes a big difference. Also the PH will drift up over a couple day period but that is a big jump in 24hrs. I use well water out in the country and it’s hard water so like 300ppm from the tap and it takes about 3-4 days for my PH to stabilize but it’s slowly goes up like from 5.5 to 6.5 in a day or 2 and each time I have to add more ph down it’s about half of what I had to start with.
I use tap water the ph comes like 7,25 and 7,50 .

When ever you add nutrients you lower ph
I have no personal experience with Advance Nutrients as they are to pricey for quantities

My nutrients aren't Advanced Nutrients but Advanced Nutrients of Holland its a different made.
The EC is nearly 400ppm and its stable, my grow is on veg phase one week, auto flowers Critical and AK47. Now the ph is more stable but everyday i have to put a little down. Temperature is about 28ª and humidity 52%. I'm watering the plants 2 times a day, is enough? I have a picture

if the correction is in the range 0,1-0,3 nothing to worry about.
Your ladies are too young to make any correction. Wait until the next res change and see what happen.
Try to follow this schema.
Have an happy grow !
