hey there , during veg in soil the best thing to remember is less is more, you do want in general three categories of nutrients at all times : NPK, cal mag and a chelation agent. NPK is basic fertiliser, you're looking for a ration similar to 2-1-1 in veg and 1-2-2 for the NPK respectively, it will be displayed like this on the label. cal mag is necessary for cannabis even in soil. it turns out these "high quality genetics" just cant live optimally with naturally occurring cal mag. finally the chelation agent, this is what breaks down long chains of nutrients into smaller chains that are bio available to the plant. this can be humic and fluvic acid or beneficial bacteria, try canna boost or biobizz top max , greatwhite or hydroguard for the beneficial bacteria. Then you want to pace these : do one feed for every two plain water waterings minimum. follow this pace and you'll have commercial grade product . hope this helps ! 🚀
