Leaves drooping

Hi all
First grow. Plant has been really healthy looking but today leaves are drooping. Temp got up to 35 degrees Celsius in cupboard today. Have 4in intake fan and 6in exhaust fan. I've watered pretty much daily but only about a cup as have been super cautious with overwatering. Water still comes out the bottom of the fabric pot with soil/perlite mix. Using Greendream bloom nutes with every 3rd water just straight water. Flowers still seem happy as. Is this a simple case of not enough water. Cheers

Looks like you have spiders buddy, second pic plant has webs on it.

Ya I see webs

I think your under attack

Thanks guys, never even noticed. I'll get some organic spray and apply. Any homemade remedies out there? Will the plant bounce back when treated or can it be terminal.
