Max Nute PPM for Ebb & Flow

GreenGrin · Feb 1, 2009

I've searched these forums and Googled the question with no definitive answer. Given the following details, what is the maximum nutrient concentration (ppm) I should risk?

Ebb & Flow hydroponic
400w HPS
White Widow
Five weeks into flowering
Using CNS17 Bloom with Liquid Karma
Canopy temp averages 75 deg. F (65 - 80)
Filtered tap water about 75 ppm

I have read stuff like 800 - 1200 ppm range; 1500 ppm; and one guy says he maintains his nutes at 2000 ppm. I refresh my reservoir with 1200 ppm solution every week and top off with plain water daily. Wondering if I can get more yield with a higher nute concentration.

Thanks.

i personally do veg as 1.5EC (1050ppm truncheon), then ramp up to 1.8EC (1260ppm) for first 3 weeks of flowering, then usually step up to 2.0-2.2EC (1400-1540ppm) as a maximum..

2000ppm seems a bit rough, but i could be wrong...

hope i havent made this worse..

Thanks so much Codwalop! What you say makes solid sense to me. I thought it might be best to push the nutes during bud growth.
Thanks again and again.
