No they look fine lke everything some plants come on better then others but the picture looks fine get a light has close has possible.get a couple of flouresents and get them a few ince of the top the plant will soon get it's next set of leaves and shoot up.a grat tip is if you live with someone who knows your growing have a week on week off thats how you see a differance get some water set at 5.5ph and make 1 ltr up put 1 drop of multithrive in don't feed it anything else untill it has its next set of leaves i leave mine on this feed for 3/4 week.
