Heyy Raptor A good way to feed when in soil is to do a schedule of Feed-Water-Water-Feed It works very well with almost any nutrient brands👍 And you probably want to start feeding around 3-4 Weeks into the grow and start out with like a 1/4 Strength of whatever nute brand your going to use. The reason I say 3-4 weeks is the soil has enough nutrients in it to carry them along for the first few weeks no problem👍Happy Growing!!🙏
