Agree with mr. Burns you have to feed that plant. Those directions are for a plant in let's say a 10 gallon pot then you may not have to feed that soil then, but you're going to have to feed it in a 3 gallon pot, you should have been feeding it quite a while ago, also to get your pH Down mix your nutrients up to around 500 - 600 ppm (500scale) and feed it at about 6.2pH to get that pH down a bit cuz 7 is a bit high, good luck!
