Unless that coco's from Kokomoko,
Addin' stuff is jus' plain loco.

Seriously, there have been side by side grows with and without perlite added.
It was not needed.
Nor is gravel in the bottom.

Drainage and tilth are near perfect with quality, (I prefer Botanicare), coco coir.

I will advise that there are different brands and that some coco is unrinsed.
That "natural", on da label worries me.
If you don't have a ppm meter to test the first run-off water, the easy test is to taste it.
If there is any saltiness, flush with plenty of water before using.

You will need calmag in any case as coco has none.
Add a tsp. per gallon and maybe 1/4 tsp. nutes to the water you use to expand the brick.
Adjust the water PH to between 5.2 and 6.4 and never let it dry out completely.
Then stand back, weed loves coco.
