Could you add a photo of the entire plant?

Are they in pots?
If so, what is the pot filled with?
How do you decide when the plants need water?
How do you water? by hand? sprinkler? drip? or?

It's in a 5 gal container, with Supersoil. I water it by hand, and how much depends on how hot the weather is. Everyday when it's real hot, but usually every other day.

Although I've picked off the discolored leaves, other leaves continue to discolor. But at the same time there is a long nice green healthy looking branch growing on the same plant. I expect that some of it's leaves will discolor, but right now it's full and green.

I'm trying to post another photo showing the entire plant, but it's in an awkward place and hard to photograph. And I'm having trouble with the one photo I took...when I try to post it here it flips over 90degrees, on it's side. I'll keep trying, since it shows the healthy branch.
