Growing question

Hello, If you're soil growing with a decent soil (like a foxfarm or similar) I can usually go at least 3 weeks with nothing but ph'd water, sometimes longer. Then you can bring in some low dose well rounded nutrients. I think having a small dose of a calmag supplement is a good idea on top of other nutes, my plants got a lot happier once i regularly used calmag. If you're growing coco or hydro or other soil less mediums you need nutes from the 1st week on...especially calmag with coco, although I'm not exactly sure why that is. Good luck with your 1st grow. Definitely try out a photoperiod when you can, they're much more forgiving with time frames...able to fix mistakes before it's too late, take clones etc.
