Around day 19 I first noticed pistons to show on all of the plants. Growth was good, the Cookie was by far the biggest in terms of leaf size and foliage however they were all around the same height. I started some LST on the Kush and Gorilla. Also started feeding some veg fert this week. Only small doses as I am a novice. I had mixed the soil with some humus, guano and fishmix before potting.
