I planted these 2 sativa plants in a 65 gallon pot a month ago. The leaves on the one plant have become super rigid, and started to curl up. The other plant, not so much. I have another pot directly next to it and those plants are doing great. Planted in soil with a compost blend and a drip irrigation. They all get 8 hours of sun. Northern Napa temps. Any help would be SO appreciated!!
