...ok..every time you grow you need to set your room up and so you should have gotten in your empty flower room and checked for leaks, you should have timers also i hope...looks like you may have some leaks because that should be doing something by now, i THINK this can be caused by high n but not sure on that..also if your going to grow again learn to lst and keep your lights very close to get a nice canopy, get an hid for flowering because its hard to pull off anything worth while without one. grow in organic soil with organic nutes, no miracle grow no schultz 20 20 20!! tap water needs to sit out a day or two before using.. those are my tips off the top of my head because i could write a whole page of instruction...
