ya, in most cases you want a reflector, unles you have a small veg chamber with white or mylar surrounding

you wont notice a difference until you get a reflector, but you are loosing out on some lumens that will make your plants grow faster

as for the plant, it could need more P.. i use superphosphate to get my roots nice n strong or even a good 6-3-0 mix might help such as blood meal... tho i am not an expert in the field, i just started my first grow as well.. zandor? can you verify my diagnosis??? :rasta:
