Week 5
At the beginning of the week I set up and tested auto-pot system for 2 plants using the same reservoir of feed water. All connections work fine with no leaks, the floats are free moving and work as intended, I have air pumping into the reservoir and all connections are good there as well. I used black tubing for the feed lines and placed towels over he reservoirs to block out light from the water in the system. After all checks were made, I placed the plants in the pots and turned the system on.
At the end of the week I had 3 new nodes of growth since the last topping, so I topped for the third time (4 cuts this week on the 4 set from last week and also removed the lowest). I now have 8 colas set.
Feed this week was 400ppm total before add-ins. I used 360ppm Veg concentrate mix (recipe week 2) and 40ppm Bloom concentrate mix (recipe above). However, I also added 1ml/gal of CaliMagic (General Hydroponics 1-0-0) to all feeds and ph balance this week was for 6.3.
Next week will consist of training the colas to go where I want them to. I plan to train 6 to the outer ring and 2 to the inner ring. Once I have enough new growth I will set the tomato rings and possibly start wire training. Feed will increase in total ppm and bloom mix and I plan to reduce ph to the 5.8 range slowly, so about 6.1 this week and 5.9 next before flip on week 9.
