i would say just do a reg. transplant roots are pretty damn delicate and fucking with them will almost certainly cause shock if u have a really strong root system u could take it out of it's current pot, hose all the soil, off, then put the plant, sandwiching the roots system between the soil
bud side effects of this may cause death...........
trying to change the soil cuz the stuff im using now is not workin out keeps way to much watter and stays wet for so long got new soil that im trying to change to would it be better to just put new soil over the old in a new pot....doesnt sound like it but if its better ill do it
