Started a plant in miracle grow potting soil inside under 2-65 watt full spectrum led floods. I built a 30"x 30"x 65" grow tent and added a supposedly 5000 watt full spectrum led lamp with 2 exhaust fans built in. Using bottled water when soil feels dry. The plant is thriving. Up to my 4th set of 5 leaf branches. About 3 weeks from sprouting. My question is when I replant to a larger pot, should I use more of the same soil or change at that point? This is my first grow and want to keep the science easy. Outside its easy to get creative with additives and fertilizer. Never grew inside before. Heard many pros and cons about MG. Would it be a shock to change soil at that point? Any help would be appreciated.
