Im about 6-7 weeks from seed. I started off using miracle grow moister control potting soil in a 2 liter all the way till last week when transpanted them into a 3 gallon.I just found out the soil isnt very good for the plant when i switch into flower should i let the roots grow for 1 more week then wash off the dirt completely from them and put new good soil? Or would it be better to keep this one is veg and make clones off into better soil and flower those then keep this mother plant in veg?
Best to use growing media from a grow store. It has microbes and other goodies. Fertilized stuff means you don’t control the nutes schedule or strength. Best if you control what goes in plant. Auto’s will do ok in 3 gallon pot. 5 gallon will do better.
