Indoor gardening is still gardening so it certainly counts! How long has your aloe been in the same pot? For indoor plants I like to either up-size the pot or prune roots and repot periodically. It helps to keep them from becoming root bound and strangling themselves - not saying that’s the problem but it could be a factor. If it were water stress I think you’d probably be seeing signs on more than just the center.

For your hyacinths, try top dressing them with additional soil or mulch to start. Sometimes it’s the planting depth that is impacting whether they fall over. If you’re feeling froggy, you could consider testing your soil, particularly for potassium and calcium. Calcium is used in building the cell walls and the potassium helps to regulate how firm/turgid the plants are. Boron plays a role too but it’s a trace element and not a home test I’ve seen much.
