I don't think it's magnesium problem. Also not a calcium problem. Is it a lower leaf and has your pH been on point.

Just had a look at your diary. Have you got plenty of drainage because you plant looks a little over watered. Make sure you get run off when u water.

Yellow spots on lower fan leaves
Hi Growers! First grow here and I am concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg deficiency? N deficiency? Too less water (100ml every 3days)?

On Week 11 Day 74, I've been noticing the leaves turning yellow. I'm assuming because we're getting close to harvest, but after reading more about nutrient deficiencies I'm wondering if I should be doing something about it. I started flushing a 1.5 weeks ago.
