She stopped eating

Greetings all...
Hydro, ebb and flow. shes in a 10 gallon tote bin with a 20 gallon res. gh flora nova nutes @ 1300 ppm. Ph drifts between 5.7-6.2
bagseed sativa in week 10 of flower.
All was well until around 4 weeks ago when I saw some spotting and discolored leaf tips and edges.
A little cal magic & kool bloom seemed to help, but the past 2 weeks she's not taking in nutes at all. She is still taking in water, about a gallon a day. Ppm's stay the same every day after top off. Just flushed a couple of days ago & I have her at half strength nutes at the moment.
Any thoughts as to what's happening?

Maybe she went on a diet.

Hunger strike

Last grow was 14 weeks... Don't have pics at the moment, but she def still has a few weeks to go.

hm, well...she's locking them out for a reason...
I caused lockout with calmag recently...but that was in soil....

Just FYI, I don't know if it means anything but...in my hydro grow that finished in January, I noticed that about three weeks away from the end they stopped taking nutes. At first I thought it was a lockout, so I did a full res change, but that didn't change anything. Then the fan leaves started fading. And I realized that they were just finishing -- at some point, they're not getting fertilized and it's all over. I just kept adding water, because they were drinking water, but I never had to add nutes again because the PPM didn't change.

So, I think your strain is more sativa-dom than mine, so 10 weeks sounds like they're finishing, and the not-taking-nutes seems normal to me.

Also, it made me realize there's no need to "flush" if the plants stop taking nutes on their own and you let them go until they're ready for harvesting.
