Ive been away for a while and unfortunately not because of being horticulturally active.

I have GH nutes and i forgot what ppms i should use for veg and flower. i can get the ratios of grow, micro, bloom from the GH website.

SO what are some tried and tested ppm values for a bubble bucket (DWC) type system?

I start my clones out in a DWC with a ppm of between 300 and 600. depending on the age. the youngest clone i will put in there is 2 weeks old. hope that helps

this is my answer. dont know if its for dwc or flood and drain (both)

Week 1 - PPM: 0
Week 2 - PPM: 0-300
Week 3 - PPM: 3-500
Week 4 - PPM: 5-700
Week 5 - PPM: 7-900
Week 6 - PPM: 9-1000
SWITCH TO 12/12 LIGHTING AND BLOOM NUTES (this is just an example you don't have to switch to 12/12 now)
Week 7 - PPM: 3-400 (note the drop after switching nutrients)
Week 8 - PPM: 4-500
Week 9 - PPM: 5-600
Week 10 - PPM: 6-700
Week 11 - PPM: 7-800
Week 12 - PPM: 8-900
Week 13 - PPM: 9-1000
Week 14 - PPM: 10-1100
