Many growers rule of thumb is Feed nutrients every other watering. But determining when to start feeding and how much feed can be puzzling.
According to FoxFarms there is sufficient amounts of NPK to support 4 weeks of vegetative growth. The same recommendation is made for FoxFarms StrawBerryfields. After 4 weeks FoxFarms recommends beginning the feeding of Macro and Micro nutes. But then the question is : How much nutrients do I give the plant.
I use
FoxFarm soil mixes
Happy Frog (Veg) and
FoxFarm StrawberryFields (Flower) and I adhere to that recommendation. I also use FoxFarms 3 part nutrients and the feeding amounts vary from plant to plant. Have you reviewed FoxFarms feeding recommendation charts ?
I also use Sensi
CalMag. During vegetative stages I do not add
CalMag to my
HappyFrog soil mix.
After transplanting into StrawBerryFields (5 gallon bucket) at on-set of flowering I begin to add 2mg
CalMag per gallon with every watering and feeding. I've found that to work well for me during flowering.
