This is a really good houseplant fertilizer. I have about 30 plants, and this one box will last me 3-4 years or more.

no its not. its one of the worst you can use. The problem with MG is that the nitrogen is derived from synthetic ammonium and water soluble nitrates, producing off-chemicals that are harmful to soil microbes, worms, and all other forms of life in the soil. potentially leading to nutrient imbalances and a buildup of salts in the soil. It doesn't contribute to long-term soil health and sustainability. Your soil could become dependent on constant synthetic fertilizer treatments. You get better long term results using a better quality product. your soil will last longer, produce better and use minimal fertilizers.

Organic fertilizers (sometimes sold as "slow release") require the bacteria in the soil to break them down to free up the nutrients leading to less getting washed away and less shock to your plants. Synthetic fertilizers are in a form immediately available to the plant, so you'll see a quick response, but it doesn't support soil bacteria/fungus long term. Those things are actually really important to have in your soil, as they have a symbiotic relationship with the roots of the plant.

Synthetic is great when you're trying to maximize production and minimize crop cycle times, but it leads to long term damage to the soil. Like, let's say winter is expected earlier than usual this year, and your crop usually comes in a week before winter. You might drop a synthetic fertilizer to speed up development in order to get that crop to produce early vs entirely losing it. A perfectly fine solution for one year, but not sustainable in the long term.

A perfectly fine solution for one year, but not sustainable in the long term.

All of this is valid, but for houseplants in relatively small pots, the use of synthetic fertilizers is perfectly acceptable. Given the indoor conditions, there are no worms and minimal bacteria and fungi due to the limited amount of soil. Using synthetic fertilizers will require you to repot or change the soil less frequently.

The downside is that your plants will become dependent on synthetic fertilizers, but in many cases, they already rely on supplemental nutrients since they are in pots.

You shouldn't be depending on soil for nutrition in house plants, most of my plants don't even have soil they are just coco coir, perlite, and vermiculite, which is why most people use fertilizer in the first place. I have used this fertilizer for 20 years and every year I am shocked at how fast my plants grow in the spring when they come out of dormant.

5lbs would last a lifetime for the average person with a normal amount of houseplants.

Agreed.
Outdoors I'm using compost and mulch to feed my plants.

Indoors it's a potting mix with limited ingredients. This would give that instant spike needed by the plants

In for one

If you are not in a hurry, wait until fall for clearances. Walmart had the 5lb for $8 in some stores. Of course YMMV. Their EG brand is 5lb for $4.50 in my area.
