SOIL Yellowing\Browning leafs - what's wrong?

[kobe]

Hello Growers,

hope all you doing fine. I need help - I'm at blooming stage and my leafs seems have a problem. They are starting yellowing, browning.

I'm growing in soil and using 100% Terra.

Could someone help me, what's wrong with my flowers?

Thank you.

Lots more info. How close are those lights, how strong watts from the wall? Don't feed till this is corrected no more Nutes this looks like over done ferts. Plain light photo of whole plant please.
