They are ok for now but look for them getting yellower or showing spors on leaves. It's usually either a lack of nutes (for example nitrogen if they are light green/yellow) or sometimes too much nutrients (for example if they are too dark green, almost with a blue tint). There are charts or pictures that describe all that online. Some threads on the forum as well. Or you can post in the infirmary and get opinion of more experienced growers.
