I have 4 plants outside in full bloom. They are in separate locations. My soil usually has 6.8 ph, never above 7 or lower than 5.5. I feed MG tomato food every 2 weeks. They get bug sprayed once a week with different types of sprays, mostly organic. Since my leaf tips were also dying, I bought a fertilizer meter. It said all were low on nutrients and I added a lot more MG tomato food and some blooming food with less N. It look a lot of these to get the meter to say they were enough. I made sure it worked by trying it in a pot of miracle grow pre fertilized seedling soil. The meter works fine. The only thing I can think of is I didn't saturate the soil when fertilizing... not sure if I am supposed to?! I have tried flushing the plant in the pics, it did nothing.
For the past two weeks, my flowering plants have had their pistils die and turn brown. They start dying from the tip to the base and on all buds. The pistils all pretty much dead now. I've looked all over the internet and have posted in several forums about the pistils and dead leaf tips, but have few answers and no ideas for this problem. Someone said nutrient burn for the dead leaf tips, but my nutrients were very low when I checked. These are only into 4 weeks of flowering and no one yet seems to know what is wrong! :-(
What causes the healthy white pistils to suddenly die?
Can I still save these plants and buds?
If not, should I let them keep growing, harvest what little there is, over even try to make the plants veg again? (most are too large to bring in, but digging them up and cutting 1/2 of them off might be possible)
Please help! This is my first grow. These were started in May, first signs of sex in mid September. The pistils weren't alive long enough to turn orange... just dead. :-(
Here's the photos.
The first and last photo are of the same plants, 5 days apart! Second pic is also of the same plant
The 3rd pic is of a 2 week younger plant that was in the middle of dead pistils.
Except for dead leaf tips, a few yellow leaves, and a few white flies, these plants look healthy. The plant in the 3rd pic has no signs of bugs a all!
