But yeah once you’re in full on bloom I’d crank it up to 6-800 if she can take it. I never went above 1000 on autos at any point.. but some can take more than others
Ezzjaybruhanswered grow question 3 years ago
She looks happy and not underfed at this point. Being an auto you don’t wanna go too high. I’d bump it up to 550-600 and see how she does. No res change unless things look dirty. I’d do a res change in 2 weeks once flower has really set in.

If you're using the GH 3 part I recommend doing a full water change right before switching to flower. Also 400ppm's sounds low to me. I'm usually around the 1200-1500ppm range in bloom, but I follow the Lucas Formula which only uses the Micro and Bloom nutes in a 2:1 ratio micro to bloom. Are you using any supplements or just the GH 3 part base nutes? What kind of water are you using?
