I’m hoping I can get some advice regarding my current autoflower grow. I am currently growing:
- Indica Autoflower
- 4 weeks - Just starting pre-flower
- Soil - Coco Perlite 70/30
- PH In 5.75, PH out 6.2
- PPM’s in runoff 900
- Watering/feeding every other day
- Nutrients - Jacks 321 at 3/4 strength
Problem - Leaf Issues showing yellowing and some brown spotting…Not sure if this is calcium, magnesium issue? I do add a little extra cal mag with the Jacks epsom salts.
Have 4 Indica photo periods with these and they are not showing the same leaf issues,
Any feedback or recommendations would be appreciated
