Really curious about multifeed hydro grower's experience using 6/9 or Lucas formula with LED and co2 supplementation.
1. Does the Mag become an issue with LEDs even if you multifeed or run DWC.
-Can increasing the EC alone correct the issue?
-In your experience, does running Epson or a magnesium sulfate product handle it alone
-As long as pH and EC are in line, while multi feeding, does Mag deficiency pop up at all?
2. How far have you pushed EC with 6/9 and/or Lucas with LED?
-When did you start to see problems?
-Is there a point where you stop increasing base nutes concentration (EC) and supplement Mag instead?
I ran 6/9 with fulvex to supplement magnesium for years, non sealed, HID lights, with co2 supplementation, with no issues. Sealing up my first decent sized room, and wondering if I'm going to run into problems due to the lights.
I should be able to keep the room 82-85°F and between 62 and 70% humidity, with maybe a 4%rh swing. I should be able to make anywhere between 400 and 1500ppm co2. And I should be able to make anywhere from 400ppfd to 1200ppfd averages on the canopy with the lighting.
Any pointers or caution would be greatly appreciated. I really like to plan plan ahead.
