Leaves Burned

My dina fem blue hash's leaves are burned looking. 4 weeks into flowering

I am using ff ocean farm soil, used no nutes until last week started molasses
yesterday added some tiger bloom 1/4 strength

Today they look worse.

I flushed this morning. What kind of deficiency is she showing?

Maybe its just the pics but it doesn't looked burned to me. It looks like your plant is starting to turn a bit purple.

It is getting crispy on the ends.
I need a good ph meter.

Here is a better picture

I'm no expert so take this with a grain of salt, but isn't brown/purple'ish hued leaves that appear to be drying/dying indicative of a Phosphorous deficiency?

yeah im pretty sure that's correct but these leaves look like brown spots some kinda nute burn looks like...
