i personaly dont do soil grow but in the book it says u want to keep ur soil at a 7 ph lvl, so ur pretty close, i dont see ur ph being the prob if its that close, give her a lil more nitrogen and keep an eye on ur new growth for signs of any deficiencys, all strains are a lil differ and may ask u for a lil more of differ nutes at times. u should also think about getting a cannabis grow bible. i got mine at barnes and noble for 28 bucks but u have to ask for it, they keep them behind the counter lol
