New dwc grower needs help.. Whats wrong with her??

Hello Everyone, Hopefully Someone can help me with my Girl.
I am using advanced nutrients Iguana Juica Grow and advanced nutrients Iguana juice Bloom.
I put her into flower 3 days ago, all of the big fan leaves started curling inwards and looking old/ weathered yesterday.

everything else is looking great (so it seems)

Lights are 2 x 150 hps
constantly 4 inches from the top of the plant
Times running are 12pm-12am
Sleeping during the night.
Do you think it is getting too cold at night for her down there in the wine cellar??

I think I may have been under feeding her.
I was using 15ml of Iguana Juice Bloom in 30 litres of water.

I found the Feeding Chart/Calculator on advanced nutrients website for all of there Products.

I just put an additional 45ml of Iguana Juice Bloom into the Resevoir.
Was This A Good Idea??

Do some strains just look Hideous??


Thanks For Your Assistance.
Cheers !!
