Anyone help quick ?

Ok so last week my plants had extractor fan turned off and heater left on so my bottom fan leaves went yellow and limp as heater on floor . I think I have some other deficiencies as well as heat stress I just need some help diagnosing them.

I’m growing in soil in tent with 600w hps and last water I put a mix of cal mag and water with ph 7 and run off was 6.5.
I added nutrition about 4days before this with ph 7 and run off was 6

We'll need a whole plant pic for a proper diagnosis mate...

....they look overfed, burnt tips, off color,... lowers may not even be heat damage, but if it got very hot, it may magnify the issues,... HPS is terrible for diagnostics, we need normal light pics please, color rendering is very important for this! :smoking:.... pH might be off as well,... your input pH is too high, but run-off is coming out much more acidic, hinting at acidic off pH in-pot....
