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.

Chan, I purchased an aquarium heater and I am looking to warm my solution in the tower garden. What temp would you suggest?

So I’ve heard basil grows really well on a tower garden. Mine is not. I have a few healthy leaves but the new ones coming in small and reaching maturity . They have this brown discoloured look to them. EC 1.6 and ph 6.0.

Hey guys, First of all: great to be here, I was always inspired by Hydroponics and Aquaponics. I'm located in Germany and I want to buy a tower garden using Chad's affiliate to get also the nice course from Chad. This question goes probably specifically to Chad directly or to someone who already did order a garden in Europe. Can someone help me? I'm having this link here. How can I use Chads affiliate code (to also get the course for free), but order it from Europe if you just click on the link and it doesn't work? Thanks in advance.
