Are u feeding your plants? Be honest, the tips of your leaves are pointing up, this tells me u jacked ur plant on something, flush your plant IMEDIETLEY unless u want to burn ur plant to cinders, good choice with the northern light a very forgiving plant perfect for new bees, purple kush or purple haze? Both strains need much more attention, when u do decide to feed, use less u can allways give a plant more food, once a plant gets burned u can' unburn it. SNOLEPERD ps if you need help in future just ask
