New growth lime green ?

White Widows , soil , HID lights , temp 79, humidity 55%, 3 weeks give or take couple days . At first my white widows were off to a terrible start . I\'m a new grower so I didn\'t have enough light . But once I set up and bought the necessities they seemed to be doing great . Here\'s the question and because I\'m new at this don\'t judge me . Open minds ... anyways. Should I be worried about the new growth coming in so lime green . This is new to me so I really don\'t know if I should be concerned amp;#128563;
