Could someone tell me how to add photos please?

Are you using 420 app? They can't be added through 420 app anymore.
Download 420 app then add 420 magazine. Here's a screenshot.

What kind of pk boost did you give it? Cause some brands aren't meant to be given till the end. It can kill your plant I've read.

Looks to be nitrogen. Bloom nutes are lower in nitrogen. When it starts at the bottom is most likely a N deficiency.
Yeah i was thinking that too,ill see how if they get any better giving it a slight dose of veg nutes with the bloom,my biggest problem is i took too many leaves off so hopefully doesnt get worse quick
