Leaves bright green on late flowering plant

God damn guys, you're so good at answering questions! It is indeed a bit warmer in my tent because of the current heatwave (it's around 26C). @Danski do you mean a 6.5 PH for hydro or soil? Because all I read about the right PH level for DWC was 5.5-5.7

I wouldnt be worrying just feed water and they will start to yellow up. They look amazing anyway

I wouldn't worry about it this late into flower your plants are alomst done you should be flushing now anyway and your plants leaves naturally start to fade off as the plants end is near but in future do regular water changes and raise your PH to between 6-6.5 and lower your PPM to 800-900 this is the sweet spot for me.
