Oh man not sure what it could be... Ca+Mg, P ?
Bit my F13s looked a bit similar.
It's something that I have found happening to me frequently when I started growing with LEDs.
Have since added extra bonemeal and kelp to my soil mix which sorted it out, but not always it seems, and then I never know wether i've got too much in the soil or not enough.

Maybe something entirely different as it also got really cold at some point in flowering
Good luck man

It’s a bitch when problems like this occur...
My OGx Snowman #1 is turning yellow on the tips of the fans. But only on the branch’s that are right under the light...
As I said before, the three Snowman crosses I have in flower are literally 3 inches under the light hood... from putting them in too tall to start off and then they stretched a Lil....
I’m guessing it’s the lights being so close that’s causing this to happen to the fan leafs. I know when lights are closer it will rise the plants metabolism if that makes any sense ???
I'm thinking a combo of things.Too me, that looks like a P def. Looks like they didn't get enough for some reason? Good it be they just got to dry for a short spell?
