Hydrosystem: Atami Wilma 8 drip irrigation with hydroton
2/8 plant have this problem. Temperature has been bit high (80f). I use GHE flora with Lucas formula + calmag + bloombooster. Its 5th week of flowering.
PH has been mostly between 5.7 - 6,2.
The EC started to rise quite fast 1.5 -> 1.79 (in one night). So I did change the res, flush yesterday.
After that the EC dropped from 1.29 -> 1.19 during last night.
From the symptoms of your leaves, it's a little bit like calcium deficiency,cuz there have brown spots on leaves, But paradoxically, plants usually don't need much calmag after the 4th week of bloom.
I found that the leaves and tips nearest to the light, has burning symptoms, Normally, in the last few weeks of flowering, about 690 PPFD is usually required.
and ur EC started to rise quite fast in those weeks, and I have learned that some commercial growers in hydro tend to decreased slowly and kept about 5.5 at the beginning stage of Veg in the last few weeks of flowering。

The best way is to do your own calculation and get your PPFD through DLI calculator,
And then watch her reaction, she will tell you everything it needs,
Cuz everyone's garden is unique, no one can give u specific answers .but science can
