Batch 1 Shutdown (88 days old)
The system before Shutdown.
No matter how often I trim off the outer leaves, the yellowing continues to propagate. As for the Lollas, browning along the leave stems are accelerating.
Reason? The persistent "fungal" problem, shown below.
Red Oaks looks OK though. So it's likely the water is not healthy in some ways, though EC shows 1040. Didn't manage to measure pH.
8Mar update: A fellow UF member shared this site on leafy plant issues. Dengarden. Looks like Yellows.
About Yellows
Yellows is a fungal disease caused by Fusarium oxysporum con-glutinans, and triggers formation of large, dull yellowish green patches on the leaves of vegetables.
The harmful microorganism survives in warm conditions, which means that you can prevent it by keeping your garden at lower temperatures. The disease can be spread by farm tools, so ensure you clean and disinfect your tools before using them in your garden.
The best way to control yellows is to plant certified seed or disease-free seedlings. You can try to kill the pathogen with fungicides such as Terraclor, Captan, and Thiram.

Harvested a colander full of good leaves for dinner.
Sime sticky white sap has been observed for past 2 weeks. Seems like it's normal. Latex based substance. A quick search revealed the sap is save for consumption. In the past the Romans discovered tvat this sap, though taste bitter, has sleep inducing properties. So lettuce were served at the end dinner meals to help diners relax and chill! Read here.
After full harvesting.
Added 50ml of 3% Hydrogen Peroxide to each tier of the system to clean the system of algae and any potential microbes. Let the pump continue on to circulate the mix over the week.
