good question :thumbsup: ... this is where beginning growers screw up their plants ... yes, your plant will be getting it's nutrients from the soil, but may benefit from more 'food' ... don't fertilize at all, the first 2 weeks ... then, after 2 weeks, I suggest you use a good, mild fertilizer, and half-dose it, once per week ... it's always easier to add more, than try to correct an over-fed plant ... Fox Farm is my current favorite, but the BEST plants I've ever seen in my life, thrived on plain, old Miracle-Grow :wtf: ... whatever you can afford, but don't hesitate to dilute from label instructions, with any product ... good luck :jointsmile
