Is there truly any benefit to buying cannabis-specific nutrients? I've been using Miracle Gro Tomato (0.5 tsp in 2 gal water) with great results. It even contains a pH buffer that automatically adjusts my water from 7.0 to a perfect 6.2. This stuff is super cheap ($6 for 1.5 pounds) and seems to work well, so I'm curious if anyone sees any drawbacks here. Any reason to buy the expensive stuff?
