Clueless, Help!

Ok so this plant is a month old. I have been lst'ing it because of space. It has been through sigficant heat, 120 F for a week at one point. But now averaging 95 F lights on, 73 F light off. I have to water every other day because the soil drys out fast. But i give it nutes every other watering, the ratio is 18-7-8 or somethin close. I plan on flowering it next week, its a female bagseed.

Anyway I have a problem that I bet can be easily identified but I can't figure it out after my research. The trend starts in the older fan leafs, first little brown spots, then eventually it spreads further and larger in between the veins. And now the whole leaf is now turning all yellow and drying up, very brittle. Also leaves are droopy but im pretty sure thats the heat problem. I would appreciate any help and sorry about the blurry pics. Thanks.

why are you tourturing plants?? could be heat stress or sometype of insect? looks like leaf is rotting

Im not tryin to...this is my first grow and im on a budget with cfls and a rubbermaid. I havent seen any insects....

Its not bugs, its too much nutes, flush that shit!

You have humidity issues and there's a fungus on your leaves. You need to bring humidity down and get an organic fungicide spray to kill it, like Safers. Cut off the affected parts of the leaves to keep it from spreading before you spray it....they aren't coming back once they're crispy.

Yeah man I have also seen this problem a few times before it is DEFINITELY a nitrogen deficiency! And since you have to water so much because of the heat I bet that you have flushed a lot of the nutrients out....You need to add more!

But seiriously though dude go buy a cheap exhaust fan or something the room should never be more than 85 but ideally it should be 80....

I just run plain water in my hydro buckets for the last two weeks so the buds are already curing before they are off the vine....By the time I pull them off the are so ripe but the leaves are yellow....It always starts in the older leaves and takes over most of the plant by the time I am ready to cut them down....Oh it makes the smoke SO SMOOTH! I suggest it to anyone...

Probably heat stress. And to much of a temperature fluctuation can kill a plant. Get that heat out of there and get a fungicide.

thanks for all the replies. i am gonna go cut off all the bad leaves and get some fungicide.

and jimmy you might be right about accidentally flushing out all the nutes cuz my soil is 50% peat moss...

and i can't fix the heat i already got two fans one intake and exhaust.

but thanks again. i will report back the results later.
