I'm getting my bucket ready for a DWC. The tree is small and has been in dirt inside the house. Can I use a large pool noodle rather than a 10 inch net cup with clay pebbles in it for supporting the tree?

I have a question for you... This spring and summer while researching which plants to grow, where to put them, container size, sun exposure, etc. I learned how some plants grown together are beneficial to each other while others are harmful. An example is how tomatoes grown with basil can actually change and enhance the flavor of the tomatoes. Is this also true for a hydroponic/aeroponic environment such as a tower or nft system? In the same respect, I learned that some plants deplete some nutrients while other plants add those nutrients back. I cannot remember the specific plants or plant combinations, but I wonder does that also happen in the hydroponic/aeroponic environment? I also learned that there are plants that, if grown too close to some others will actually kill them. Again, I don't remember the exact plants or plant combinations where this occurs, but does it happen in a multi-plant system or plants growing in the same tent?

I want to grow spinach on my indoor TG. Do I just use the same EC, pH, Temp, etc as kale, lettuce, arugla?

So in my quest to narrow my problems down, I was having a look at my seedlings. They are around about day 11 from germination and I’ve been adding my filtered water only. I noticed the dill had gone purple (and read it was a sign of stress). I also noticed some of the leaves slightly yellowing already. What I can’t remember is this normal? Do they look like healthy seedlings at day 11 or not? Tonight I added half strength nutrients. @Chad Miner what do you think? My previous seedlings I bought RO water and used that.
