Week 3 continued... using sodium bisulfate for pH down is a big no-no. Especially with plants this young. I would suggest not doing so and switching over to a more natural phosphoric acid like what you can find in most hydroponic shops. However, I am prone to using minute amounts of sodium carbonate, or baking soda, when the situation permits.

Switched over from a Age Old Grow mix of 12-6-6 which the helpful person at my shop suggested was a bit too high in nitrogen to a more suitable 3-2-6 Fox Farms Hyroponic solution. Also, you may notice lock out on the lower leaves of the plants from the previous pictures you can tell this has now been adjusted.
