You should try to keep the temps below 85. Are you pHing the run off or nute solution before watering?I dont think they are mature yet. So 3-4 weeks more. I just flushed them with flora kleen, 1/2 the pot size input water.

Looks like nute burn in combination with heat stress, especially with the curling symptoms. How much ya feeding every watering? Full dose? Half dose? 1/4? And finally what soil ya using? Your soil could already have nutes, making it unnecessary to add anything through much of the grow, besides maybe CaMg.
I assume "AN" is advanced nutrients? Not familiar, but I've read many biased opinions. Sticking with organic is the best advice I was ever given. Age Old Grow & Bloom have both worked wonders for me.
I would lay off the nutes since we can rule out pH problems.Input water ph: 6.4
Output water ph: 6.1
I'm feeding them 2 ml/l of micro/grow/bloom which is %50 strength. 5 ml/l gh ripen. Soil is Biobizz light mix with extra perlite in it. I'll try to switch to organic with michoriza etc.
I managed to get them stable at 29 c today. Flushed them with Florakleen. Pots are 8 litre, i flushed with 3 liters of florakleen added and ph'd water.I would lay off the nutes since we can rule out pH problems.
Maybe an extra exhaust fan or opening the grow room every now and again to get some fresh air.
Your plants aren't to far from being done, and the problem may become unfixable at this point, especially those dying yellow leaves. Just keep an eye on new growth. And test Ph of run off.I managed to get them stable at 29 c today. Flushed them with Florakleen. Pots are 8 litre, i flushed with 3 liters of florakleen added and ph'd water.
