Nowhere to stash stuff. You'll have to sell or destroy things. My guess is that you have an inventory stuffed with Ores, Gems, Plants and Potions.
My recommendation is to sell off Ores, Gems, Plants and such that you don't think you'll need - which grant bonuses for equipment that doesn't interest you.
Get rid of your smaller potions that have the small boosts, you can only have one potion of the same type active at a time.
Get rid of your Iron Ore, Moonshine, Holy Basil, and Oak Tears, as they're all useless. If you need some later, it's easy to find. You can probably also ditch your Droxlerite, and Fossil samples as well.
