Please can someone tell me what's going on with my plants? I'm container gardening indoors with T5 flourescent lights for non flowering plants (basil, spearmint, head lettuce, leaf lettuce, kale), and with an LED grow light for kale, arugula, carrots, 3 types of tomatoes, cayenne peppers, bell peppers. All my seeds are heirloom/organic/non hybrid.
The first problem that I started getting was wilting in the swiss chard and cress I first started growing (and have since abandoned). My leaf lettuce (Black Seeded Simpson) are all laying on the soil and the stalk on one of them is turning brown:
Does anyone know what's going on here?
Here's another picture with a different problem. One or two of the leaves on my head lettuce are starting to turn brown:
What is this and what causes it?
I also have noticed "stuff" start to appear on my soil (mostly around the edges of the pots)...I don't know how to describe it and I had a hard time trying to capture it on camera:
(it's the brown stuff...but I think it starts out white)
Here's the last picture of my kale (Siberian Dwarf) that started out great, then I noticed the 3 original leaves start to yellow and they've now shriveled as you can see in this picture:
And now one of the other leaves looks like this:
What on earth is going on with my plants??? I started out with beautiful seeds, germinated them before planting in premium potting soil that was mixed with worm castings and Azomite.
My tomatoes, peppers, carrots, and two other kale plants (in the closet with the LED light) are doing great (so far) but I want to avoid having similar problems with them so any insight that someone can provide would be greatly appreciated.
