What am I looking at?

I have been suspecting something fungal, but my fungicide has had no effect (Cease - Bacillus subtilis). Any ideas? The plants are roughly 4 weeks old and are just now starting to really crank up flowers. The issues are only on lower leaves...all thoughts are appreciated!

Do you have an Ag Extension office nearby. You can take a leaf sample to their offices and have one of the master gardeners take a look. Once they determine what it is they can tell you how to treat it.

I'm not convinced that that's a fungus, especially on such a young plant.

What growing medium did you start them in? Are they growing now in containers or in the open garden? If they're in containers, what kind of potting mix are they growing in?

Doesn't look fungal, but looks very much like insect damage.

Mites? have you a magnifying glass?

I have the same thing happening to my tomato plants. The whole month of August was dismal for tomatoes. Hardly any good fruits. The affected plants were the ones getting the most sunlight. This might sound weird, but maybe it was caused by the Sun giving off cosmic rays. The Sun is going through a change in polarity and .... Heck, I don't know.

A little more info...these are in a greenhouse growing in coco coir fed via drip irrigation/hydroponics. Given the time of year, fungal disease is definitely a concern.

Could be mites, but I can't see them...will get a magnifying glass. I do have some spider mites on other plants that I just knocked out.

I may head down to the extension office, but you never know what you will get. I generally trust the pool of knowledge online over one person sitting behind a desk.

Cosmic rays? Hmmm

[Bogaat]

Ok, I have confirmed two pests. I found both thrips and leaf miners. My current thought is that the above damage is thrips? I found some other types of damage that are definitely thrips...hoping they did this as well?

[Bogaat]

Just found some whiteflies on another row...man, I am getting slammed! Spraying neem on all rows today.

Good to know there's a down to earth explanation and not cosmic rays.
Great pictures BTW. The dead giveaway that bugs were at work were the scraped away leaf tissue on the bottom of the leaves.

Ok, cosmic rays weren't to blame for my tomatoes going kaput. I dug up one container and found a lot of grubs in it. I made a Sevin solution of 2 tblsp per gallon of water and poured a gallon into each and all my container plants. Grubs came out of the soil as they died. Lots of earthworms also died, sorry about them.
