First Grow with pics... need some help!

I have 2 Bubba Kush clones under 2 42 watt 6500 as well as one 68 watt 2700k. They are abut 20 days into flowering and I have starting to use bloom boost and molasses. Just wondering what everyone thinks as well as looking for some feedback on the pic here with the leaf starting to look discolored. Thanks!

Too much nutrients. Without a doubt.

they were in MG soil while vegging so I thought that might happened, the leaves looked like this way before i started with bloom boost or anything, the nutes in the soil were very calcium heavy but i did flush them before starting bloom booster... that should help?
