I've tried everything to correct this problem. I've maintained a solid PH level in my waterings, I've built an organic soil, and I don't overfeed the plants. They are showing some kind of deficiency. My initial diagnosis was Phosphorous deficiency, though I'm sure I added enough bat guano and kelp meal into my soil to prevent that.
Anyways, the plant is not showing signs of getting better. The lower growth is affected quite exclusively and the sickness is traveling up the plant.
I've watered with some medi-one and bloom formula to see if a phosphorous deficiency could be reversed. I think my other plants have responded well, but the Northern Light strain is continuing to show these brown spots and the lower leaves are drying up and falling off.
Any ideas?
The strain is Northern Light.
temps: 75-82
Humidity: 30%
