Hydroponic systems typically use a balanced, water-soluble fertilizer that contains all the essential nutrients plants need to grow. This type of fertilizer is specifically formulated for hydroponic systems to ensure optimal plant growth and development. Common ingredients in hydroponic fertilizers include nitrogen, phosphorus, potassium, calcium, magnesium, and various micronutrients. It is important to closely follow the manufacturer's instructions for mixing and applying the fertilizer to prevent nutrient deficiencies or toxicities in the plants. **

The white spots in the terrarium water are likely to be mineral deposits or residue from the water source. These deposits can accumulate over time as the water evaporates, leaving behind the minerals. It is important to regularly clean and change the water in the terrarium to prevent the buildup of these deposits. Using distilled water or water that has been treated to remove minerals can also help prevent the formation of white spots. **

It is important to maintain good oral hygiene practices and visit a dentist regularly to prevent and treat these spots on teeth. **
