Thanks for the response sorry I am so late with my response back a lot of stuff going on around my house. I had to hide my grow for a yearly inspection where I live. lol Now to answer your questions. I was giving them nitrogen but on some of the older leaves there were signs of nitrogen burn so I stopped. I then moved onto a more natural grow with the new soil that feeds plants but I am thinking that isn't probably reliable but what do ya expect from a newb lol. There were brown tips on some of the leaves not all. There is a fan but no exhaust fan because this grow was in a walk in closet so I figured there would be enough air. I check on them throughout the day when the lights are on and if it feels stuffy I open the door for a while and it clears the air in it. Again this is a rather large closet so stuffiness doesn't happen too often. They are in flower and have been for about 4 weeks the new growth is looking ok but I am concerned about the older leaves with the claw like curl. I heard that it could be a ph level problem but it is hard to check if it is too low or too high since I couldn't find a ph tester for soil in my area.

I will fill out the troubleshooting form but wanted to touch base first and answer your questions. Again thanks for the reply.
