My colleague replied to you browntrout:
"As for the soil on the farm.... I use G&B organics potting soil and G&B Harvest supreme amendments. I add the amendments after the potting soil deplets the nutrients... usually about 60 days I start top dressing with amendments once a month. I also use General Organics products plus compost tea was used once a week...... hungry girls... they ate a lot...lol! I miss those beasts! Hope this helps."
Dubi, I think the tea is the ticket here. I've fed very similair happily growing plants that were very yellow with lots of manure teas and had similar results.
Will update next week, lots of vigor in this one. She smells fruity/citrus with some slight spicy/woody notes right now.
Funny he mentioned this strain being hungry, I put it in a large pot with some compost and time release fert/lime, and gave it some smaller feedings on top. Bottom fan is starting to fade. Surprising! I've been kinda scared with my Port Saint John, SA sativas that show a a slight tip burn with feedings, but the Auto Malawi loves it!
