Most nutrient manufacturers today want you to use many different types of chemicals to do something simple- flower a plant. Most of these chemicals are non-organic so they don’t naturally purge out (using bio catalyst) which causes the plants to end up packed with trace chemicals. You can start by implementing organic ingredients into your cycle to replace the non-organic ones. If you really don’t want to change the nutrients, than flush 7-10 days with a salt leaching solution. Here’s a Tip: You can try letting your flower dry on the sticks if you are not already doing this. You will most likely see, smell, and taste a difference.
