You can make growing as simple or as complicated as you wish. Here are some basics for fertilizing your outdoor cannabis grows that work well for us.
Pre-Planting Field Amendments
All-purpose dry amendment (5-4-3, 5-3-2, etc.) - for large scale growers, between 500 lbs and 2000 lbs per acre depending on spreading technique and planting date
Feeding Seedlings in the Greenhouse
We use all-purpose fish/plant based liquid fertilizers (5-1-1, 4-3-2, 3-3-3, etc) us at half strength, after week 2 of plants being above soil – work your way up to full dose if plants do not burn
