PROBLEM??!! PICTURES....... Not sure?

I have read many thread on curling leaves, as well as similar problems like mine ... SIDE CURLING UP..
My dignosis: Heat - the box is vented and sits around 30C ( around 80F) I know that its high, I have placed fan inside box as well as AC for 2 days bring temps down to 26C...with no result. This was a ducted system and too expensive to run full time..... its peak summer here,,,,,so it on when the house needs it not the "tomatoe" plants.
Any ideas theorys, and more important how to fix?? THANX CHAPS & LADIES

Running a FIRM 5.8 PH
useing DUTCH GOLD a+b
Aussie majic grow jiuce
super thrive

pretty much all us hould do at this point. should point out that if these leaves in the pics r new growth, usually they will flatten out over a day or two

Some are some are not.... and its random over the plant not defined to the top middle or bottom..... But you could be right they are in a growth spurt...... suckin alot of juice at mo.... i might chuck another water cycle in too..
