Hey guys, here I have my little plant that has started to develop some problems. She's about 3 weeks old being grown indoors. I'm using rapid nutrient system and she's under a mars hydro 400. She has had this problem since she was about a week old but now it seems to be getting worse. Any help would be great thank you :)

Rapid Nutrient System?, what's that.. Did you feed the plants before the first three weeks? What type of soil are they in, and did they start in a different soil? Have been you putting anything on your soil such as Molasses or Coffee Grounds? I see terrible pH fluctuation signs and from experience I know what causes that but the response depends on the why.
