How can i increase bud quality?

I've been using TPS Signal (a potassium-based electrolyte solution that increases flower density and hardness. It enhances terpene synthesis and supplies the essential forms of potassium that plants depend on to uptake water and keep their metabolic rates elevated during the late stages of bloom.) It has really made my buds smell and taste outrageous. Good luck with your grow. 🌱😎👌

For my gorilla grows I normally just use base nutrients. Most the time it's just water. I only visit them every few weeks so it's a bit hard guessing what they need till I see them. If you have any nutrient products you use just use them.

You have an outdoor grow. You may need to add a cover for bad weather in flower. Planted in the ground is the best like you did. The best thing you can do for the quality is a proper dry and cure at harvest.👊
