Co2 from the get but I've seen the mag issues before with elevated co2.my last run I was pushing the mag and calcium to hard and locked out other important nutrients.i was running 5ml per gallon of calmag and it was just to much.Heisen u running C02? If so what PPMS? Was told by someone those yellow tips and mag def go away under cobs when running c02 as long as obviously you arent lacking Mag and Cal. I havent turned mine on this run yet but had very similar thing while vegging. I added epsom salts tho and it fixed this under the cobs little bit before flowering. Have perfect tips now an dno C02 yet. I usually turn C02 on around day 20.
I dropped it to 2ml this run and kept part a to b the same and the plants are happy.ill start getting the yellow tips on the leaves when the ppm starts to rise with lesser amount going in with the top off res that's how I know theres a lock up.i flushed and dropped to 390 system and 400 res and everything is good again.
I'm running alot of air in a small system with a vigorous top off setting so my plants grow retarded.anything over 500 ppm cooks the roots.
Editing this in I can hit 600 during the stretch cause the plants will drop the ppm daily from eating so heavy during those 3 weeks but after the stretch I always see a rise in ppm.
they are sitting in a highly oxygenated soup so they dont need much when the environment is rich.12 plants taking in 5 gallons of water every 12 hrs.not drain to waste them bitches are thirsty
