Foliar fertilizer feeding is a simple way to deliver fertilizer that contains healthy nutrients through your cannabis plant’s leaves. While foliar feeding will never replace root-feeding programs that add much-needed fertilizers, foliar feeding does provide a quick boost and is known to increase a plant’s yield. Regardless of what some people believe, cannabis leaves do need regular and adequate misting, and there’s no better way to do this than to feed your plant adequate fertilizer through its foliage.  

Every cannabis grower, should use an effective foliage feeding program, using the steps listed below, to make sure your end-result is an increased yield:

How much to feed – never too much and never too little. The leaves should not be soaked, but just adequately moist.

How often to feed – cannabis plants should be “misted” every other day.

How long to feed – foliar fertilizer feeding can be used throughout the plant growth process until late into the flowering period. This is because the residue from the feeding remains on the plant at a time when you are preparing for harvest and consumption.

When to feed – the ideal temperature is anything lower than 80 degrees, with 72 being the perfect temperature. The best time for foliage fertilizer application is around sunrise and sunset, meaning beginning at 7am and ending around 5pm.

Clean leaves – because of the residue on the leaves, they should be cleaned before the drying period begins. The leaves should also be cleaned periodically to prevent the stomata, that absorbs the fertilizer, from becoming blocked.

Type of sprayer – our best advice, at 13E, is to invest in a quality sprayer that will deliver a fine mist.

pH level – the pH balance for your foliar fertilizer should be maintained at a level between 7 and 6.2.  Adding baking soda to lower and vinegar to raise the pH level can help.

Signs of leaf distress – the number one sign that a cannabis plant has received too much, or too little, foliage spray surfaces in the leaves. Either leaf discoloration, leaf curling, or even dead leaves could be from an incorrect amount of one or more nutrients. “Nutrient burn” indicates too many nutrients.  Inexperienced growers are more likely to believe that the more nutrients the better, but this is not true and can cause more harm than good. Lack of nutrients also has its own set of problems. Plants, like any other living organism, must have the proper balance to reach their maximum potential.

When it comes to foliage fertilizer and high yields, just remember, moderation in all things applies here as well.
