What up Kush, You've got several probs bruh ! A couple more pics of the whole plant would help with the diagnosis. You're slackin ! Why did you wait so long..he,he,he .NPK and Ca/Mg is at the top of the list, along with micros Iron,Mang,Zinc. If your in veg I would transplant, and keep your PPM's and PH at recovery levels, around 700 ppm's and ph 6.2 to 5.8 . I would also spray a foliar mix of Kelp and Epsom salts and keep it below 300 ppm's. GL
