Hello, I am on day 13 of my first grow. I'm using Coco coir/perlite (70/30), mars hydro tsw2000, 5 gal pots (filled to 4 gal of coco). Currently cultivating two Grand Daddy purp, and two blue dream.

I've been given 1.5 ml of calmag per gal of water(ppm around 230) pH to 5.8.
Light is dimed to 50 percent at a height of 19 inches. Light cycle is 20 on, 4 off.

I think I'm doing it right but I'm not quite sure. The only thing is the plants look a little light green in my opinion but I could be wrong. Is it possible to overwater Coco? Should I be giving them nutrients yet? What's your opinion?

I wouldn’t be using so much cal mag. I’ve used 3-4 tbs over the last dozen years. What npk nutrients does the soil have and what npk nutes will you be using?

Are you using tap water or RO?

You should feed them. Coco has no nutrients in it. Start off at a low ppm of 200-500 of your base three nutrients skip the cal mag for now follow GH schedule as a guide http://greenbookpages.com/general-hydroponics-flora-series-feeding-charts/
P.S. your tap water likely has enough calcium in it for now at a reading of 170 ppm.
