Mega low ppm in flowering...?

Hiya
Heres my RQS Jack Herer auto a few weeks into flower...temps/pH/RH all normal. Its just ppm, she's been put at 600 a few times now and id expect that to drop, but with her it creeps up slightly, 50 or so over 24 hours. Sorta suggests to me shes not really feeding the way she should be...?
Previous growes have levelled off somewhere in the 800 - 1000 range. 600 just seems very low. My water is about 180 so only 400 of actual nutes...
She seems happy enough, maybe shes just not very hungry...?
Any ideas?
Cheers!

This was unhappy with 600ppm.

I usually max at 600ppm on most strains.

Cheers, i think my max was about 1200...i guess each strain is different!

Some strains do not require high ppm and some do. I would not worry as long as she is happy. Wish you the best with your grow.

you could get that high with an auto?

less money on nutes=more money for beer

Cant remember exactly maybe not 1200 but certainly 1000.

It's weird that the bottom leaves are nice and big and the top leaves are not. Something is out of whack.
