Ideally you want to be around 6.3-6.6, some people would offer slightly different targets for soil but it works well for me when I stay in that range. There is a wealth of information on this site, check out the sticky threads (permanent threads) on the top of the various sections. I've only been here a few weeks and I've learned sooooooo much more than I've read in any book, all from other people's hands on experience. Flushe'm what are you waiting for ;)

Also if i have a fan blowing 24/7 while the light is on and temps are still too high, how would i reduce the temps?

can we get a closer picture of some of the less damaged leaves? some times when they are that far gone it is hard to tell what caused it. definitely trim off the bad ones. i think you have nute lock out due to imbalanced pH. it is safest to feed every other watering to prevent buildup in your soil, but many people feed with every watering and have great results. whether its lock out or burn, flush your soil and give them 1/4 strength nutes at the proper pH. most nurseries sell a simple soil probe that reads your pH and moisture content. for your nutrient solution the pH Kit from General Hydroponics comes with everything you need and should last quite a few grows.

All the fan leaves are pretty much yellowing/starting to yellow. By trim off, do u mean just take off the dead crusty brown bits or just take off the fan leave all together?

do you have any way of pulling air from around your canopy and exhausting it into an other room or out a window? or of bringing fresh air into the room? is your lamp in a hood or reflector or do you run an open bulb?

yes completely remove any leaf that is more than 40% damaged, take clean sharp scissors and cut off any badly damaged leaf tips. these areas are a breeding ground for pests and diseases.

you got heat stressing as well nutrient burns goin on there lift your lights higher the brown leafs on very bottom of plant are dead dryed up leafs i would assume IMO i would clean up your plant lower leafs as for the burnt leafs leave them on but there good as gone i would leave them on till next watering so plant can take what ever juice out of them but there goin to die so pull them next watering
As well get lots of water run a ph of 6.8 and flush them plants run the water thru soil and once you did it check your run off ph good luck go easy on nutrients

im sorry to say that if you dont find a way to exhaust the heat from your light you are going to continue to have heat issues, especially if you are in the northern hemisphere. you can get a decent 4" inline fan for about $100, 20' of 4" duct is about $25. there has to be some way you can exhaust your heat even if is just to get it out of the closet. an oscillating fan isnt going to move the air the way you need it to to cool the room.

Yeah, def need to lower your temps. Wouldn't hurt to raise your light a couple inches for the time being to relieve some stress until you're done flushing. Get this bish dialed in!
