Heat stress in Flowering, any tips?

Fed them yesterday:

Maya Ivar Clara
Water total / Runoff 3.0 l / 0.1 l 3.0 l / 0.3 l 3.0 l / 0.1 l
Nutrients 100% Flower Week 7 + 3.6ml CalMag 100% Flower Week 7 + 3.6ml CalMag 100% Flower Week 7 + 3.6ml CalMag
PPM (in/out) 1.400 / 1.650 1.360 / 1.450 1.380 / 1.580
pH (in/out) 6.0 / 7.2 5.9 / 7.1 5.8 / 7.3

Honestly don´t know how the runoff pH can be this high again already. But i won´t be able to flush again, no time. Maybe something else is off since they start to yellow again. Especially the top one, which is also foxtailing quite a bit it seems:

But they also are pretty far into flower according to the seed bank (45-55 days flower period)
Also visibly starting to seem pretty mature. Top and right one are fairly far on browning pistils. Only the right one seems to just start now with browning pistils.

Top one:



Right one:



Left one:



So maybe the yellowing is part of the late flowering process.

@OGIncognito can i get them through until harvest like that? I´m willing to take loss in quantity/quality but I can´t really flush again :sweat_smile: They look far along in my eyes. They filled out nicely and smell a lot. And the pistils are also on the way (except the left one)

Cheers
