dude u dont need to switch the soil...its already rooted in that and u can damage the plant if u fuck the roots up...

u probally wanna have the lighting schedule 18/6 untill u put it into flowering and then u change it to 12/12....ull know when to change it to 12/12 cause the nodes will be alternating which is a sign of maturity

when u feed ur plant that means u give it nutrients...

water your plant well every few days...i did mine every other day because my grow rooms temp was slightly high...

post some pics i wanna see what ya got
