Well i have been hearing to much about these mag issues with GH, i need to get a new nutrient line going to use on the current winter-spring crop so i know how to use them on the big crop next summer. Advanced is to expencive i need 1000 gal every other day for all summer and the 2 months of flowering. Canna has been suggested Anyone have any suggestions? The plants will be in 300 gal smart pots and shounld get 10 to 15 ft tall so i need a good prooven mix. What do you promix guys use? Im really worrying about this, i cant afford for a whole crop to go to shit, i only get 2 a year so there isnt much room for experimenting.
