I'm looking for more taste than quantity in t...

cheap alternative to expensive sugar-based bloom boosting supplements is blackstrap molasses. Giving this to your plants for the last few weeks before harvest can help them get bigger and smell/taste better. It’s not specially made for plants; it’s the regular stuff you’ll find in your kitchen or at the grocery store). Blackstrap molasses adds sugars, amino acids and trace minerals. Unfortunately for hydro growers, anything organic like molasses is not suitable for a hydroponic reservoir! But molasses works great for soil and coco growers. For the last 2-3 weeks before harvest, give 1/2 tsp of Blackstrap Molasses per gallon when watering (for soil or coco coir). Also a proper dry and cure will bring out the best taste in smell in buds.

There's a lot of myths in the web, so I would not buy into whatever you read. If flavour is your goal, do try to keep the grow as natural as you can, organic is the way to go. Get something like worm castings and ammend your soil with it; also you can make it into a tea and fertilize with that instead of bottled nutrients. Another alternative is bat or seabird guano, it's a pain in the ass to dilute, but very good too.

Be careful with internet research, there’s a lot of bullshit. You will never increase terpenes with a stress ! The first thing to do is to put your light far enough to not burn all the essentials oils. The next thing is to use the less nutrients as possible by giving them the right amount. And finally, flush them correctly and entirely before harvest.
