Directions should be on the bottle, yah?
But yes, with coco, every day.
But PH is important .
Coco is kinda like solid state hydroponics.
Loved the results using Dynagrow so much that I now use DWC.
(Deep water culture) Just a 5 gallon bucket with an air pump and a netpot.
Because there is much more room for roots without the coco.
The Dynagrow was not very stable. would precipitate the salts over time.
Switched to Mastergrow, Epsom salts, and Calcium nitrate. I adjust the PH to 5.5 - 6.0 . Hydro and coco like a low PH.
The results are outstanding.
Vegging under LEDs and blooming in Hawaiian sun.
Be happy to assist you.
