PPM keeps dropping 2 wk flower

Hiya
Heres my Strawberry Cough 16 days 12/12. She looks fine except i was at about 800 for veg nutes, since then it keeps rising 100 or so, so bring it down a little, it goes up, i bring it down and so on. Eg last time, 758 up to 840 over 12 hours, so shes at 650 now, and it will probably rise again.
Ph very stable 5.9-6.4
My first time with a photo (normally do autos), does this seem normal, i mean she should be sucking up more nutes if anything...? Shes gonna be down to like 200 at this rate!
Cheers!

What are you feeding her right now? If ppm keep rising and her ph is in range then you're feeding her the wrong nutrients. If in flower you feed her veg nutes for example something similar will happen. Also take into account she's been in her stretch phase which tends to utilize more nutrients.

Are you measuring after topping up? Plants always take more water than nutes. Measuring is done after topping up with water to give the effect that PPM is stable at the right range. That ppm rise seems perfectly normal if you just letting them drink. It could also be the plants taking up less N which is a significant portion of the mix.

ph values for hydro are 5.6-6.4,so 5.9-6.4 a bit on the high side!!

Cheers, definitely bloom nutes, Canna hydro. I take a reading before lights on at 6am and after at 6pm.

Girls are just thirsty, drinking more than there eating.

Stable overnight 570. My water is about 200 so that's actually only 370 of nutes...man that seems really low for a girl about to explode into full on flowering.

She's just moving a lot of water through her vascular system.
What are the environmental conditions?
I would make nute decisions on what the plant is telling me.
Is she happy???
Showing any signs of deficiency or toxicity???

After lights out when she is zipped up, RH is pretty high 70/80%, temps 25-30°. Plant seems very happy, no signs shes missing anything.
