Seafood for nutrients? N check out my purple elephant

How much nitrogen do you think would be in crab water? The guts and what not. Would it be easy to burn my plants with it. I have a 2 ltr. bottle with nice seafood juice oyster shells and crab shells I plan to put around to keep away the slugs I've been battling. Thoughts? This is a purple elephant baby doing good.

Those are some massive fan leaves for a juvenile. But sorry I can’t help with an outside grow, I only grow indoor. The only seafood source is use is kelp ( seaweed ).

Put out bowls full of beer around your plants....slugs will go into that and want nothing to do with your plant
