Barneys Pineapple Express

The plants are growing quite steady, I am noticing new areas for potential bud growth. I did cause some unnecessary stress on one plant in particular due to over watering. The plants seemed thirsty so I watered them two times 4 days apart with about 3/4 gallon each time. The first time was just water, the second time I added nutrients. So far they seem to be responding well, the tallest plant has grown to be 17 inches and the shortest is 13 inches. I plan on putting up a trellis next week and rearranging the tent.
