Hi and greetings from Florida. This is the first year I will be using premixed bagged soil from Fox Farm and my plan is to grow in 5 gallon fabric pots which will be bottom layered with a mixture of Coco Loco and the upper half of the pot layered with Happy Frog. My understanding is that the nutrients in the Fox Farm mixtures have a limited life and before the plants have reached their full life-cycle (4 plus months in my case) I should augment the soil with additives, which I’m planning on using Mega Crop by Greenleaf Nutrients. My issue is when I should start to add the additives, I’m thinking around mid vegetable stage. Last thing I want to do is overfeed the ladies. I’m open to any suggestions and thanks in advance.
