[Teh Teong Chian]

Hi,

 

Just realized my tomato plant having these spots on the leaves. Anyone knows what is it?

Also i have these Chinese Cabbage( choy sum) growing and some of leaves are actually curling down.

Is it normal?  And leaves at the bottom touching the clay seems like have slight burn spots.

Hi Teh,

Could be a number of causes here. I suggest posting a full reading of Ammonia-Nitrite-Nitrate,PH,Water Temps, Fish feed brand, cycle time, fish-media-water ratios and anything else you might think important.

I found this resource on the web and there is even a contact at the bottom you can ask questions. Anyway let us know how it turns out.Thanks.
