very true this is down to the lack of chlorophyll in the leaves which makes it harder for them to photo synthesize so they need intense light 2WPGRed plants tend to be more demanding that other plants in my experience. (of course, this is a general statement). May need more / better light, but of course as soon as you do that you'll be opening up a whole can of worms...
