Hey HydroScript, To bring this back fully onto topic, your buds might me a bit small, but only week 5 and 2.5 weeks more fattening may be all you need. I have general suggestions for BIG BUDS:
1) Use Tree Pots for deeper roots; they break down cases, any # you want:

These are 3.2 Gallon, but only 9" wide, and 15.5" deep.
2)Wood or Foam under the Pots, never on the ground. Cold roots make small buts! Try to run lights at night and be dark during the day to even out temps. Use HID for the heat if you must.
3)PH is critical to the amount of Nutrients your pants can tolerate. I love Miracle Grow Tomato Food, 1/2 tsp per Gallon, and 4 ml Cal Mag, and PH to EXACTLY 6.5. IF I use PH = 6.0, plants can only handle 1/4 tsp per Gallon at most!
4)PH Test ONLY using API's Aquarium Test Drops for $5. GH's test drops are shit resolution. ANY Digital Tester will lie to you! PH Test Drops never lie!
5)Use more light. Ditch the 2000 Watt unit and get several Mars Hydro SP3000's at 300 Watts each. 1200 Watts will yield 2 LBS. Use at least 1 as a side light shining down 45 degrees or even less to illuminate at least one side of your crop. Bathtub crops work best for this.
