Leaves look burnt

I’m trying to figure out what’s going on with my fan leaves they started turning this color about a week ago.
this is my first grow so I know I’ve made some errors but can’t figure it out

Have your temps been running cool at night? Cooler night temps will cause it and a lot of strains just have purple leaves because of their genetics. It won't hurt anything.

Huh no shit. Yes I did notice the temp has dropped. Interesting. I keep an eye on it. Thanks!!

Is A phosphorus deficiency possible as well?

Genetics will cause purple, as does cool temps, are you feeding bloom food of any kind?

 

[Baddfish4545]

No I’ve gone back and forth on what to use so I have not yet. What would you suggest. It’s about 3 weeks into flower

There are a lot of good choices out there, I build my own soil, and I use Roots Organics dry products (no paying high $ for water), base, grow and bloom. Base when building the soil with some grow and bloom, and then bloom in flower. Is it the best, I have no idea.
