One of my 3 girls is getting rusty fan leaves that curl upward and then die, all 3 plants have the exact same conditions and are almost 3 weeks into flower, humidity and temp. are good, Espoma Organic Bloom 1-3-1 liquid feed, growing in 12" pots with super soil mix. The buds and small leafs are still OK and have a nice citrus smell. Any suggestions?
Not sure of the soil pH, I checked the water using a aquarium pH kit I have and it's been 6.5 after mixing using a 50/50 mix of rain water and my filtered well water.. What's the best way to get cal mag back in spec.?
You could try a guarter does and foiler feed meaning spray the leaves with a spray bottle. And run a couple mls per gallon of cal mag when watering
Ok, thanks everyone, I didn't have any cal mag but I did have some liquid lime, I mixed up a weak batch and watered her well, 3 days later all rusting has stopped and the buds are looking nice with a slight orange citrus aroma, any clue what this is? Just some random bagseed I had saved.
