First up: your plant might be hungry. Imagine eating a pizza but forgetting to chew. Cannabis is a heavy feeder, and when it runs low on nitrogen, the bottom leaves turn yellow first. It’s basically the plant cannibalizing itself for energy—like skipping breakfast to save time, but way more dramatic.
Fun fact: yellow leaves are actually the plant’s way of recycling nitrogen. It’s pulling nutrients out of old leaves to feed new growth. Kind of like moving cash from your sock drawer to your wallet because you’re going shopping.
Too Much Love (and Water)
Watering is the #1 cause of yellow panic. You think you’re being a great parent by giving it a daily sip. Stop. Overwatering drowns the roots, starving them of oxygen. Then the leaves turn yellow and droopy—like you after a Thanksgiving feast, but with less stretchy pants.
Here’s the weird part: overwatering symptoms look almost identical to underwatering. Both cause yellowing. The only way to tell? Stick your finger in the soil. If it’s soggy, you’re killing it with kindness. If it’s bone-dry, you’re a neglectful plant parent. Welcome to the club.
