Added a little Fox Farm BigBloom to the mixture in case the seedlings needed a little more nutes. Was not sure of the amount the nutrition that was in the Espoma Organic Seed Starter. I don't think there is much. 1TBSP for 32oz in spray bottle. Sprayed the seedlings lightly. Only used a few ounces of water/nutes per plant.
Gorilla cookies auto was in my first grow too. it responded very well to LST and grew big and bushy because of it. I pulled over 2oz per plant after drying and trimming. I'm still smoking it and loving it. You're set up looks great! I wish you luck and if you have questions about the strain feel free to drop me a line.
