4 Northern Light - 1st Grow

Changes for this week. 1. LST: I've removed almost all LST restraints. The plants are pretty solid and I felt like I had so many restraints that they were just increasing the clutter. Now the only restraints that I have are the nylon string I'm using just to keep the canopies even. 2. Ventilation: I've installed a filter system. Now I can finally close the tent and none of that dank smell gets out. It makes a HUGE difference and it seems like my plants are digging it. My only gripe - I'm growing these in a 3x3. I wish they were in a 4x4. That would allow me to keep the whole filter system in the tent and give more room for fans. I have 2 oscillating pole-mount fans that are fine but the thin box fan really doesn't have much room and I feel like it's too close to the plants. I'm gonna go ahead and order that 4x4 I think. 3. I watered in accordance with GH's week 2 flower schedule. The only difference is that I treated my 5 gallon bucket as though it only had 2 gallons of water in it. That set my PPM right at 700 this week. Then I ph'd the water to about 6.2. 4. I don't want to defoliate because they're autos. However, there were some leaves on the bottom of the plants that were dead or dying. I did go ahead and prune those off and that helped with the undergrowth and that made them a LOT easier to water. Any questions/comments?
