Are there any tips out there for increasing yield in the final 2 weeks of flowering ---- yes thats what the overdrive is for,,, ALSO
use "Dense" by green planet neutrients
it has a NPK of 0 0 62,, this shit hardens up you nugs therefor increasing the weight/yield... in a dwc setup i use 1gram a liter in the last 2 weeks but 1 day per week only , you use this alone with water only for 24/36 hrs then empty your rez and refill with your reg neuts, for the rest of week.,,, this shit will give you up to 1600ppm of pure potassium per 2gram a liter,, under a 250 light i would use maybe .5 of a gram per liter and go from there,
