My pants leaves are curling down and cupping similar to the shape an empty taco shell makes. it's the worst around the bud sites. I am the second week into flowering. I currently hand feed fox farm tiger bloom and big bloom with a ppm of around 1050. The pH is 5.8-6.2. I am using grow rocks as a medium and running a 400 watt hps 12/12. The rooms temp runs 68°f-75°f. I have central air and a fan so plenty of circulation. The light is about 15 inches from the top. I can't post pics as I am using my phone but I can email them. please help this poor nubie.
