What is wrong with leaves

[mysidx]

bcday, the Fungicide is a cheap brand called "Garden Safe". It is a fungicide to fight black spot, rust, and powdery mildew. Also it is an insecticide and miticide.

This plant is all by itself, there has been no other plants near this one. The others I had were healthy, however I could not protect them from a light freeze.

I used Bacto premium indoor/outdoor pre-fertilized potting soil. I haven't added any other amendments except a table spoon of bone meal every two to three weeks.

I for sure have grown to hate the leaf miners, and haven't found anything to stop them.

Garden Safe3 is just a Neem Oil extract, I can't imagine that causing leaf damage like that.

How come so much Bone Meal? I would think a tablespoon in a pot once would be enough slow release Phosphorous to last the whole season.

Looking at your second set of pictures, it looks more like insect damage by leaf sucking, leaf scraping insects like mites and thrips.
Jon's pictures sure look like the leaves have been scraped by insects, fresh damage too since the affected areas are still green.

The funny thing is those plants had no insects and were isolated indoors/started indoors in a glass growroom. The spots looked a bit green in the pic but were darker. I saw it spreading in a day or two from plant to plant. I was also using Baccto Professional.

Ya, it's hard to tell from the picture whether the leaf has been scraped or if something has caused the cells to burst and collapse. I take it from your description that it is more like the later.

The key word might be the word "spray"I found out a fine mist is the best way to apply foliars.Also I found out that misting in the evenings tend to not let the plant absorb the mist properly.I go mist early mornings before the sun gets to hot and usually mist on a cloudy day and when a decent breeze or air movement is present.i have seen when over misting will pool the mix and form droplets on the end of leaves and have seen the "burn"form after this.Potato leaves are the worst to pool the mix.Looking at your leaves they are really dark green and might indicate to much fertilizers (nitrogen?remember they make bombs out of this)Sometimes in the beggining of my mater experience I tended to get anxious and over fertilize(foliar and ground).I do not water and mist on the same day either.Seems the plant will pull water up quickly and the mist is not really absorbed just pools up.After misting I will shake the plant(vibrate)to shake any excess off.

I am having a similar looking thing happening to my seedlings this year. The fall plant I referenced earlier in the thread was a full grown plant. I did not spray any neem oil on these, however I did spray a mild mix of spinosad on these because of the bad leaf miners we have here, and did not want my seedlings to be in bad shape while they were hardening off outside. You can see they are about six to eight inches tall and they were sprayed only one application about three days ago. Could it be the spray or do I have another problem? The earlier photos in this thread were older leaves from my fall plant, but the ones in this post are what the fall plant looked like in it's earlier stage. I wish someone has seen this happen before so I can be aware of what is causing it.

Neem Oil! I had white flies and sprayed Neem oil mixed in warm water on my seedlines - it almost killed them. The leaves rotted and nothing but new growth could save them. I lost 50% of my seedlings - the Neem oil did much more damage than the white flies.

Someone told me that Neem oil closes the pores of the leaves, and that is why they rotted. I don't know if that is true, but I will never use Neem oil again.

There have been no insects spotted anywhere on the plants, and I did not use any Neem oil this go around. They are still in 3" pots in Metro-Mix 380. All of the plants were sprayed with Spinosad, yet not all of them show these signs----about 50% though.

Scott, I've used a 0.5 % dilution of Neem Oil and never had a problem, but I used pure Cold Pressed Neem Oil, not an extract. I don't know if there is a difference.

I have had no neem oil problems, either. I also use pure Cold Pressed
Neem Oil, about a tablespoon per gallon with about a teaspoon of
Murphy's Oil Soap in it so the neem oil and water will mix. (I am not
trying to kill aphids, etc, just hoping to annoy insects that land on
the plants into relocating to some other kind of plant.)

I don't know if any of these problems are what you have but I thought it was very informative and found it a few months ago when looking for my tomato problem I had at the time.

Thanks Rockporter, very informative information.
