we grow rats big in SA Rupe. Once I saw a marsupial when holidaying on Kangaroo Island as a kid. I patted this thing, it was really cute. Then I picked it up and it swung around and bit me! I dropped him, at which point he stretched his body out a bit longer and it was plainly a rat. So I grabbed a fishing spear and speared it and flung it miles. then I went and soaked my pride and finger in detol lol

A few of my broccoli have survived attack from caterpillars and rats!
However they do appear a bit sick.
The older leaves turn yellow then white, and die around the edges.
- Celery is showing similar symptoms.
- Peas, beans, lettuce, chives, spring onions, silverbeet and flat leave parsley are going great.
- Could it be some particular mineral deficiency ??
- Or maybe I just don't have not enough nutes? - (I have never got a nitrate reading, but I do get spectacular growth with all other plants).
- I have been adding seasol and chelated iron occasionally.
Any thoughts?

In the interests of "Truth in Acquaponics" Hodgeshome must admit to large green catterpilla/slug things devouring cauliflour & cabbage leaves in middle grow beds where I think moth eggs are present. Outer grow beds of lettuces, spring onions, celery etc untouched to date. Peas and beans have yet to show much growth at all.
Can't suggest problem for your broccoli except does your water get much above 8-9 degrees? I wonder if these plants need periods of temp above these levels?

Aquaponicia..Scott is hosting an Adelaide BYAP get together in two weeks.
See details here:
http://backyardaquaponics.com/forum/viewtopic.php?f=4&t=3713&st=0&sk=t&sd=a&start=15
I am looking forward to catching up with the team who have now built up a huge amount of AP experience.
Be there, or be an 'ordinary' gardener. :D

Thanks for the replies on the Broccoli.
It does look suspiciously like Downy Mildew. (yep Chappo - lots of rain lately)
http://ipmnet.org/plant-disease/image.cfm?RecordID=68
I'll try a "bag test" tonight.

Aquaponica, Yes it was "1 hell of a size if its a rat"
Hope you can make it along to our meet

Ratwars - the saga continues
Caught another this morning :twisted: , however this little bugger even managed to cause me grief AFTER he was trapped.
The dog found him before I did, jumped ONTO the growbed and trashed my peas. :x

Broccoli is a heavy feeder so if lower leaves are yellowing, it could be nitrogen def. If it is downy mildew, then spraying the plant with something that will alter the leaf pH (like milk or dilute baking soda) could take care of the problem. This not to be confused with powdery mildew which milk will not help and could be a sign of potassium def but usually shows up in dry weather.

Great system. Can't wait to put a similar one together.

How big are your fish getting. Is there enough room in these tanks for them to swim around when they get to 500-700 grams. I shouldn't care that much about them because they are only going to get eaten, but a happy fish is a tasty fish.

That rat looks like he's big enough to eat my cat.

Keep up the good work.. :lol:

Thanks TCL, I reckon you are right, just lack of nutes with the Broccoli.
I performed a "bag test" for Downy Mildew
http://www.csu.edu.au/research/nwgic/ex ... mildew.pdf
no sign of secondary infection.

Gilly
Good question regarding the size of tanks and large fish. I have wondered this myself.
Some of my trout are rapidly approaching plate size and they appear happy and healthy.
Don't know how really big fish will go yet, maybe they will end up banana shaped :lol:
