Puzzled 1st timer

Hi everyone,
trawled through a few of these pages but can't seem to find the same symptoms....so here's my question:
Growing my first ever plant (white widow) in a bubble pot (DWC). Been in the pot in clay balls for 2 weeks now, approx. 2 inches tall and is dark green & healthy looking. However the cotyledons and the 2 pairs of true leaves are pointing straight up and not spreading out.
Nutrient is a proprietory one from a garden centre mixed correctly, water is clean, and am limited by space to using 3x20w cfl's. (though could double this quite easily)
Any ideas you chaps?

Thanks

However the cotyledons and the 2 pairs of true leaves are pointing straight up and not spreading out.

I experience the same thing under â??artificialâ?� low light. However, with the same plant under sunlightâ?¦no problem at all. Your present light is quite lowâ?¦..double it and you could well experience the same thingâ?¦..only to a lesser extent.

With the hydroton (clay balls) you could need Ph correction as they need to be Ph corrected before you start. Check your Ph before proceeding.

Hope that helps,
