Outdoor: Black Spots with Possible Bud Rot

Strain: Church (Greenhouse Seeds). Started from Seed.
Grow Area: Outdoor, Partly shady with sun in afternoon. Moderate climate
Grow Medium: Pro-Mix + Top Soil + Cow Manure in 3 foot diameter hole
Stage: About 3-4 weeks into flowering - Start of September at approx 45 N latitude
Watering/Fertilizer: Cheap 20-20-20 solution once a week unless raining. All other water comes from rain which is about 2-3 times per week.


Problem: About a week ago (approx. 3 weeks into flowering), 3 of 10 outdoor plants started showing dark spots on leaves and what appears to be bud rot on about 1/2 the plant, mostly near the bottom and middle of the plant. What appears to be rot (brown in color) is actually coarse and dry to the touch (as opposed to mushy like other small patches of rot i have seen). There are 6 strains in the garden with 3 that are The Church by greenhouse seeds. All the Church plants have shown the same symptoms (some to a lesser degree though). None of the other plants in the garden seem affected by this even though some are rubbing against branches of the affected plants. All the plants were started directly from seed with proper packaging. The other plants are a variety of indica/sativa mixes, some very similar to Church. I have been monitoring them for about 10 days and i've seem it spread very slowly although the initial outbreak happened within about 2 days (while i was away of course). The seeds are scattered throughout the patch (1 on either side and 1 in middle).


History: I have grown in this spot outdoors for 5 years and never had this problem. I've also been growing for over 15 years. I also took 2 of 5 church seeds and grew them indoors without any problem. I also took clones off all affected plants which have already flowered and were great smoke. This leads me to believe that it is not a problem with the strain itself or the particular seeds i got. The plants affected are close to 9 feet tall and very bushy. Other than the affected areas, they seem very healthy.


Actions: I have stopped fertilizing the plants completely and i am keeping an eye on them daily (they are close by and can visit several times a day). I have inspected the leaves and bud under a 30x magnifier and did not see any bugs or pests. I do not want to chop off the affected areas unless absolutely necessary.

Any suggestions would be great. Also, if more info is needed, please let me know.

Some strains are more susceptible to disease than others. No expert here put looks like the church has picked up something that the rest are immune too. From your description of conditions its not where or how its being Grown, or others would show signs. Hope someone comes along that has more to help ya cause dang that sucks.

Raining 2-3 times a week, how much sun do they get? Sorry I've seen all kinds of S..t but not like this one, maybe something in the ground eating roots?!?!? Any holes in the ground in the are? I don't think that's fertilizer burn, maybe it is but that much rain should wash anything up.
 
the rain they get has not been heavy (compared to other years). It will generally rain for a couple hours and then get sunny. Its actually been a great year as i haven't had to water them hardly at all and many are 9 ft tall. As for sun, they get direct sun most of the day but there are times during the day when the sun is blocked by trees on one side.

I checked the ground and there are no holes around any of the plants. Also, the drainage is pretty good as the spot was built up about 20 years ago and has a layer of gravel about 3.5 feet down (i hit it when digging).

The oddest part of this whole thing is how the brown sections feel to the touch. They almost feel like a dry bud (coarse and very dry). Yet only 5mm away, the bud is very nice looking.
