Debaser
I was out of town from saturday to monday evening. On friday I watered everything and turned off the fan because I wouldn't be around to monitor moisture levels. When I got back yesterday, I noticed a lot of leaf yellowing on older leaves. These yellow leaves weren't crispy or anything, they were still fleshy. The veins were yellow while the areas in between were sort of a translucent brown. It was the same on both Paphs and Phrags. Also, I noticed quite a few plants had their white root tips brown over. Not rot, just stopped actively growing.
My first thought was that it was heat stress from the fluorescent lights. They plants are between about 6 inches and 1 inch from the two bulb 48 inch T12 fixture (which is on for 14 hours a day). I put my hand under the lights and I thought I could feel the heat from the light even though the bulbs were fine to the touch. After all, my fan was off for a few days.
Second thought was that they are reacting to the lower humidity since I moved home from school. That was two weeks ago, though.
At every watering I use 1/4 teaspoon of MSU to a gallon of distilled water. I have yet to see fertilizer burn. Everything grows in CHC or bark.
Any ideas?
(Happy new year, by the way!)
