Plants need N P K. Don't complicate it. Run your technaflora and get yourself familiar with the operation. You will produce buds and good ones with technaflora. As you get your knowledge and experience up then splurge on more expensive products. Also, before you buying shit, write these companies. Many will give you free samples. H&G sent me their entire line and all I paid was $20 shipping. Rock sent me their line for free. Tell them you are running technaflora and want to compare.
But honestly, you will be just fine with Technaflora if you pay attention to your plants.
