ELi5: Can plants be “overweight” if they produce too much food in the similar fashion to how animals gain weight if they eat too much food?

Former commercial horticulturalist here. While my input might not be as sound as a biologist, from real world experience we basically supercharge the plants to the peak of what nutrients they are able to receive just below the threshold of toxicity. If they receive over the threshold they’ll begin to die, in specific ways depending on the nutrient. This allows the plants to bear (things) at their maximum weight, to the point that they need to be tied or else they’ll snap.

My experience in aquaculture is pretty much the same, but obviously the plants don’t gain weight, they basically suffocate if they become too dense because co2 can’t properly circulate.
