Hi All,
Looking for some help to diagnose a deficiency. A little bit of info
Growing in Coco
Led Light
Shogun Nutrients
Started as brown spots then quickly spread and became worse
Seems to have hit the top leaves but for some reason not all of the plants have this just a few of them.
My guess was calcium deficiency so I upped the calcium but nothing changed, possibly Nute lock out as the run off EC had built up a fair bit.
Thanks in advance!

Incorrect pH / overwatering / root constriction / heat stress / bad nutrients all springs to mind looking at the picture. Might be worth tapping in all of those parameters to determine the cause.
The way they look I’m Gonna guess heat stress, being it’s only at the top like it is.

my guess also 
How frequently are you watering?
