- hey i have to unknown strains(random bag of seeds) that are a bout 3-4 weeks into flowering. im using a 70 watt hps light about 18" from the tops of the plant. and an oscilating fan to help lower the heat IF thats part of the problem. ive been trying to diagnose it for a week or so now and cant figure it out. any help would be great! the leaves are slowly starting to feel crispy the tips or starting to go yellow/black as well as the edges of the leaves as you can see in the pictures. also the edges and tips are curling upwards.
