You can use any of those ferts, except Miracle Grow. Stay away from that stuff at all costs, not suitable for growing MJ. I get my ferts from Canadian Tire. They sell some organics, but they sell the most common ferts. From vegging ferts, to flowering, blooming ferts. I got my veg fert there, 5-1-1 yesterday, I got Shultz 10-15-10 and 15-30-15. So get any brand, I would use 10-15-10 first, then 15-30-15. Just so the plants get use to the ferts.

But if you have ferts in the soil already, I would only reccomend giving them a couple of SMALL doses of 10-52-10. In the last 3 weeks of flowering or so. To plump them up really nice. Other than that, they look really nice, keep up the good work!

Good luck.
