This was one of my prettiest plants. But all the leaves turned brown and fell off. Yesterday I found a soft, mushy bud top and I picked it off. It was one of the lower ones. Now looks like the same starting on a couple other plants. I can keep daytime temps in the greenhouse around 70f to 85f-ish, but when I go out there at 5:30-6am the temp is usually around 50f-60f. Today is the first sunny day we've had in over a week. Normally we're in a drizzling fog. I see a lot of purple coloring happening on the leaves, then they continue to turn yellow, then brown until wilted to death. This particular plant has been affected the longest time, but now I'm starting to see it show up on a couple other plants. All of them have "some" purple tinting. In my mind, I'm relating this to cooler damp overnight temps. I'm not sure (lack of experience) but could this be a P lockout caused by the cold? Or something else, you think? For what it's worth, I'm growing in 7 gallon containers using Kellogs Patio Plus, ewc, bat shit, blood meal, kelp, and lots of perlite. They want water just about every 3-4 days, and I water with tea made from ewc, bat shit, blood meal, and used coffee grounds. They get one gallon of tea and one gallon of water. Every morning between 5-6am I spray with 1-tsp FF Big Bloom/water in a 20oz spray bottle. I spray spinosad twice a week to keep the bugs off. Sprayed with neem oil all through veg. Can anyone tell me what the hell I'm doing?
Gross overfeeding will remove any leaves and fast, you ain't dumb either as you are very close on the anthocyanin(red food coloring) locking out, keep up your night time temps to prevent this getting out of hand, good with the Neem Oil too, and is systemic so add to your watering just avoid overfeeding, and coffee grounds will give you much agro same with molasses having them on a green house this time of year with no ample venting is dumb as the next visitor will be the bud mold angel, stay sharp with the neem as its good for mold and bugs if you get serious mold before harvest.... harvest earlier next year http://forum.grasscity.com/blog/1093/entry-9709-neem-oil/ http://forum.grasscity.com/blogs/vostok/28542-nutrient-solution-burn.html http://forum.grasscity.com/blog/1093/entry-9829-flush-baby-flush/
Vostok, do you mean that you can add neem oil to their water/food and it will be taken up into the system and will still effectively deter pests?
You are killing them with kindness - or what you think is being kind. Way too much feeding. I wouldn't foliar feed Big Bloom. You shouldn't be spraying your plants in flower anyways if it can be helped. Did you even have a bug problem to start? Coffe grounds belong in a compost pile or worm bin, not your soil or tea. Guano won't have time to break down in a tea. It can take months. Amend your soil with the guano and blood meal and leave it out of your tea recipe. My tea is water, EWC, kelp, and molasses - that is it.
I find everything from pinholes to half eaten leaves. Spraying seems to keep a handle on it. So I actually have multiple problems. Over feeding, and with the wrong stuff anyways, cold temps. I guess I was relating it all to the cold because of the sequence, everything turned purple first, then just kept on getting worse. I'm not a botanist. Air flow: The green house is open on opposite sides. I have 2 14" oscillating fans in opposite corners. That's about all the control I have. It's mainly to keep the drizzling fog off the plants, but humidity is still there. Many times it looks like it rained, but it's just wet fog. I'm gonna go back to just water and see what happens.

Many times it looks like it rained, but it's just wet fog. Fog is still the worst, as it can turn to mold overnight, regular application of Neem Oil will give great protection to bugs and mold as your first defense, follow that up with 10% bleach in a warm bath wrap plant pot in a trash bag and dip plant in Bleach solution to kill molds for the 2nd defensive tactic, messy so allow to dry under a fan Jorge Cervantes: Washing Away Powdery Mildew https://www.youtube.com/watch?v=S7jE7qzfgQs
