I wasn't paying close enough attention and barely noticed this on many of my leaves. I'm in week 6 of flower and have had smooth sailing until now. I'm leaning towards calcium deficiency. I use coco and supplement with 2.5ml a gallon of calmag. Other than that I'm using the gh flora series

If you're using RO or purified water, bump calmag up to like 4ml/gal. If you're using tap IMO drop the calmag entirely and see how things progress.

How many mls/gal of each of the trio are you using?

I always feed it ph between 5.8 - 6.2

  • Use nutrient solution that is at half your normal Inflow EC
  • Apply twice the normal quantity of water
  • Wait ten minutes following the application
  • Add additional dilute nutrient solution to produce new run-off for measure
  • Test the EC of this new run-off, it should be at or below your normal target inflow EC
  • If the EC is still high, repeat this process at the next opportunity to fertigate

Set your EC to 0.8

I use tap that's been through a PUR filter.

And I'm following the gh flora feeding chart
Micro 4.7ml
Gro 4.7 ml
Bloom 5.7 ml

So you think it's nutrient burn?
