White Widow leafs are recoloring

I hope you are having a nice day. Mine is overtaken by a mystery.

My white widow feminized, 5 weeks into flowering is starting to show some weird recoloring of the fan leafs.
I have been feeding it pH Perfect Sensi Bloom, with Big Bud, and last week I added some blackstrap mol-asses. Soil, CFL.

Take a look at the pictures as some of the leafs are recoloring. I am wondering what is going on...? I looked at the thread about the plant problems and saw pictures, but I am not really sure which picture best fit with my plant. Some of the leafs got brown tips due to a lamp falling down a few days ago..

Thanks for your help.

Here is a better picture of one of the fan leafs

looks like a heat issue

Plant is is 12/12, when lights on temp is between 24 and 30, when off around 16 - 21... Fan is going 24/7. I will turn up the fan a notch to increase air flow... No nutrients deficiency then I hope?
