Using too many nutrients can create a nutrient burn on the leaves, primarily on the [[Anatomy_of_Cannabis#Apex|apex]]
== Sources of nutrients ==▼
Nutrients can be provided to a cultivar via concentrated liquid solutions, dry amendments, organic materials, and even other organisms living in the growing medium.▼
Liquid fertilizer solutions can roughly be broken into two categories: those for the vegetative stage and those useful in flowering.<ref>https://www.hydrostork.com/npk-fertilisers-types-roles/</ref>▼
If you are trying to provide NPK organically you can check the NPK values of most organic materials at [https://thenutrientcompany.com/blogs/horticulture/npk-value-of-everything-organic-database thenutrientcompany.com]▼
==Methods of Nutrient delivery ==
Nutrients can be delivered to the plant when dissolved in water via a fine mist, this is the fastest route of administration. It has been postulated that the size of the droplets has an effect on the efficacy of foliar spray but some studies seem to contradict this<ref>Influence of Droplet Size of Foliar-Applied Nitrogen on Grain Protein Content of Hard Red Winter Wheat 2017 -https://acsess.onlinelibrary.wiley.com/doi/pdf/10.2134/cftm2016.10.0068</ref>. If possible the spray should be applied to the underside of leaves as this is where most stomata reside. Lights should be turned off before foliar spraying to prevent the light lensing through droplets burning the leaf surface.
Foliar spray should not be used to provide emergency nutrients to the plant
