Hello GC. My plant has been looking pretty sickly lately an I cant figure out what the problem is. I have two NLs growning an been treating both the same. An one of them seems to be dieing on me. They are growning in 5gal smart pots an are under an 150w HPS sunlight. The light is about 2 1/2 ft above them. They are 2 weeks an 4 days into flowering. My grow room does not have proper ventilation so the temps run between 71-84 an my humidity is around 46-56. I have a fan in there to cool things down plus I open the door every now an then to cool it down in there. Ive only watered them twice while in flower...giving them a tsp of grow big an a tbs of roots organic bloom per gallon. takes about two gallons to fully water the pot. The leaves have a leathery feel to them...Any help would be appriciated. I dont wanna have to have a burial for my girl!
