Backyard Aquaponics
A place to discuss aquaponics

Hello everyone,

I'm from Curacao and this was my first attempt with the Raft system. I've been doing a lot of research and in theory it seems I have all that's needed to have a successful harvest. But the leaves from my tomato plant are all curled up and they got these dark spots on the leaves. Can anyone recognise what this is? Where does it come from and what can I do to eliminate it.

Thank you

Split this topic out and am kicking this back to the top so more people will notice it.

Welcome to the forum

What's the weather like where you are? Sometimes when it's too hot, it'll curl up like that. Otherwise off the top of my head, lack of calcium (or locked out calcium) can cause leaf curl.

Are the spots everywhere? Or just on one plant/leaf?

We have a tropical weather here so temperatures would be around 82 degrees. The plants are in a green house so they should be fine. I also have a greenhouse with tomatoes in soil at my parents house and they grow and produce well. I wanted to try it in the aquaponic system (the tomatoes are in a dutch bucket system and my cucumbers and lettuce are in the raft system) and now only my tomato plants have this disease. I can't seem to figure out what it is.

Someone told me to try and spray the neem-oil. It didn't help at all....

Have a read through of this, it might help with the curl.

With the spots, if it's isn't too developed, you can cut them off, and dispose of (not in compost). Tomatoes rebound quickly.
