Why does my plant look so miserable?

I am deep into flowering with a mango plant that has fan leaves that look droopy and pale, some have even fell off. I let it go like this for a while because I thought it was just part of flowering that the fans look like this. But after looking at my triches and determining that there is still a significant amount of time left I am wondering if you guys had any advice for me. I am growing in Ocean Forest using Botanicare line of nutrients under a 250W HPS in a Secret Jardin that has temps that fluctuate in the 80's.

Thanks in advance
