    Leaves turning light green/yellow

    Hey guys!

    So I have recently started my second grow. I just came home from a 2 day trip and found my babies looking like this. Is it something to worrry about? They are not exactly yellow (yet) but new leaves are less green than previous ones.

    Before I left, my colleague gave them a lot of water (perhaps even too much, since the soil is still pretty wet) and they sit under a damn strong lamp (my first guess was that as they grew higher they got too close to the lamp and it's doing them no good).

    Soil used is Light mix enriched with some perlite. So far the water used was only clean water, no fertilizer. Lamp we are using is Taifun dual 200W 6400K / 2700K and they are circa 40-50 cm below it. Seeds - White Widow original. (We will start to use a fan to thicken the stem anytime now, at least for the 12 hours that older plants are out in the dark.)

    Please don't mind how the walls look (or rather don't mind the whole enviroment), it was done in a hurry and it's only temporary. Growing is not legal where I live, so it's far more complicated than it should be to get the best conditions at all time. Any advice on how to improve it is welcome though.

    (Peeking from the corners of photographs is their older brother, I can post some pictures of my first grow too if anyone is curious)

    Thanks in advance!

    //EDIT: And apart from like 14-15 hours of dark yesterday (as I said I was away and my roommate only turned the light off because we thought it's more important for older plants to get their portion of darkness, since they are already flowering, than it is for the kids to get light) they are under the lamp 24 hours a day pretty much since the beginning of the grow.

    🌱 The newest growth usually is a little lighter than the rest of the plant. I think it looks good to me If it starts getting more yellow I would worry though. Have you been checking the pH? That is the most common reason for nutrient deficiencies. They look pretty. Also, yes it is important the flowering plants don't get any light during their 12 hour dark period. If they do, they will revert back to the vegetative cycle and you will lose your buds. They MUST get 12 hours of uninterrupted darkness every single day of the flowering stage until harvest. Hope it helps!🌱
