Im starting my first grow. I've been doing a lot of reading lately about different nutes to use with coco coir. I'm looking into using the fox farm trio but was wondering if I use the trio for hydro will i need cal/mag supplement or do I only need that if using the soil formula. And also with this work for my whole grow. I'm not trying to go crazy with them or anything just a basic first grow. Thanks for any help. With all the reading I've been doing I keep find conflicting and confusing info
