Whiteflies are a common garden pest that have the potential to wreak havoc on your cannabis grow. White flies behave just like spider mites they hang out underneath the leaves, stealing essential nutrients from the plant. This results in white spots on the top side of the leaf, though most growers will notice the tiny white bugs flying around before they notice any actual leaf damage. White flies are easily spotted with the naked eye. Eggs are normally deposited in circular groups of roughly 30-40 and can be found on the undersides of leaves. When feeding, whitefly punctures the leaves of the plants in order to suck nutrients from them. This leaves white spots on the top side of leaves, which is yet another clear sign that you’re plant is infected, even if you can’t directly spot any flies on your plant. Large populations may cause leaves to become yellow or die off completely. Whiteflies usually consume more plant nutrients than they can digest. They excrete these excess nutrients as a sweet, sticky substance known as honeydew.
