Please help identify. Soil grow, week 2-3 of flower.
My best guess WAS sun damage after we sprayed for aphids with a heavy amount of canola oil (pyrethrin] during the sunny part of the day .
However, the damage does seem to be worsening since spraying 10 days ago. Can’t really be sure if it’s moving to newer leaves or not, but the burning continues to worsen.
My next guess would be phosphorus deficiency.
Soil ph is around 7.0, trying to move it down with peat moss. Soil test does show low nitrogen and phosphorus. Potassium shows adequate.
Any suggestions or advice? Thanks, Bud
