Hello,
I just put together a very small diy system involving a 10 gallon tank with 2 goldfish and I added 3 lettuce plants and 3 kale. The kale failed almost immediately, turning yellow and wilting and the lettuce held on and produced new growth but ultimately wilted beyond saving. My PH has been around 6 and I have a pretty low flow at the moment. Now, I am a super newb so I am still figuring all of this out, but I would love some advice and how to get my plants going. Thank you!
