Had a plant that looked like this . Put aome garden lime in my soil and fixed her right up
I’m assuming your soil is locking out the calcium.
A decent pH meter/pen is pretty necessary for most grows.
I know extreme makes a foliar calcarb, but I wouldn’t foliar during flower.
You really need to find a way to accurately monitor your soil pH. Otherwise it’s just guessing.

Yea man that Vivosun pen ended up being a bad buy like my lights. Live and learn going to pick up a new pen today. Did apply lime to my one plant that looks bad and did a soil test this morning and looking like I got it back within range.
Same soil after application.
I’ll post some finish shots here in the future.
Thanks guys
