Hey guys, as for when to water, I have a technique that old growing buddies taught me: weigh the pot when it's just been watered, and then when the top 2-3cm of the substrate is dry and the pot has lost 70%-80% of its weight, that's a good time to water again.
When you overwater, your plant looks droopy, and keeping the roots too wet could rot them or cause mold to appear. Letting it dry out too much is also harmful to the roots and your plant, but it’s necessary for the substrate to dry out so that it can oxygenate the substrate and your roots.
When it’s really hot and the humidity is low, a lot of water is lost through evaporation. When that happens, I try not to over-fertilize since the water wasn't consumed by the plant.
And I agree with you... less is more... 💪
