2nd Grow Tent COCO 400w Hps northern lights Nute Help

Hey guys
Ive looked all over for answers on my questions but i cant find a clear answer. Last grow i grew in soil. This time id like to use coco. I know what to do with the coco its just not very clear to me on ppm and cal/mag with coco. I want to use the canna coco line of products. I have order my ppm ph meter. What type of watering shedule should i stick to and what ppm should i be using
Thanks

Canna coco is very fine, and might old A LOT of water, you might want to mix 50/50 with coco chunks. or add some perlite.
Since coco gives you the best tasting herb, i'd opt for Organic nutrients as well. Maybe Canna or even Advanced Nutrients.
I can't tell you how much to feed your plants, as it depends on many factors, but remember, Less is More.

Will you run RO water or straight tap water? Tap water won't need any CalMag, but if you run RO water you will need some for sure.

Last grow we used rain water most of the time or ph bottled water

I purchased northern lights and got wappa, sensi star, sour cream, warlock, chronic, motivation, and sour kush for free. Just need to pick when to germ and what to germ.
