Hey guys here are some pics of my plants they seem to be rusting i picked off a couple of these rusting leafs but its starting to go to the top of my plant now..

the leafs are really dry.. what is my problem? it gets really hot up in my attic BTW

could it be nute burn or heat stress??

is it Nute burn forsure?? im using Dyna grow 7-9-5 came with my bubble ponics... but i just ordered a ppm reader.. so i have no idea what ppm is at.. earlier today i checked the temps up in the room and it was at 100.5! could this just be heat problem or is it nutes frosure?? ill have to get an a/c i think..

hard to tell......cannabis breeding with two hybrids is complex
the only way to keep a plaant under 3 feet in aero is to keep topping and tying down......super haze,so it says

well my res temps are fine and my roots are looking good.. its not that.. all my grows have had this rusting going on. i just cant figure out what it is.. roots are hard and white some a little yellowish. at night it cools down in that room its just during the mid day if its hot here.. i have them in the attic right now temps in the attic are at 76. but ive seen as high as 100.5 your next guess would be that its nute burn??

yes
do u have ppm meter....if so...u can tell how much nutes ur plants r using by taking a reading,waiting a day and take another one,if it is higher u need to add water,if it is lower u need to add more nute solution

I don’t think it is nute burn. It appears that the necrotic spots are almost totally occurring between the veins of the leaves and the veins themselves have remained dark green. A magnesium deficiency will give that appearance and it also begins with the lower leaves. If the necrotic spots, if the leaves are left on, possibly turn from yellow/rust to white and/or the leaf tips turn up it is likely a magnesium deficiency.
　
When necrotic spots between the veins in the leaves begin with the upper leaves it is then likely a manganese deficiency due to large amounts of magnesium in the soil but since the necrotic spotting seems to have started with the lower leaves I would say a manganese deficiency is rather unlikely.
　
If it were nute burn the tips would almost always dry out and discolor first and then the edges farther down the leaves would follow and that does not seem to be the case going by your pictures. Also it would not only happen between the veins of the leaves as it appears to be happening by what can be seen in all but one of your pictures where one leaf has more severe/advanced necrotic spotting.

I also do not believe it is only heat stress since that would not only show up, or mainly only show up between the veins of the leaves or start on the bottom leaves and would instead show up more evenly over the plant. The veins in the leaves also would not remain dark green as your veins for the most part appear to be but high temperatures could be worsening the problem since your temps are most definitely to high.

ill try and take some more pics later but omg my attic temps are out of control now.. its been hot here the last few days and its just lingering at 96 degrees supposed to stay hot like this for next week too i think it drops to 85 at night like right now.. feels like a sauna up there. i bought some mg pills awhile back and threw one in the res.. can i over feed them MG? if not ill throw another pill in there and see what happens. the water is warm really warm never noticed it like this before.. the roots are all still holding up good but i think with this much heat they will become soggy.

i dont have any A/C in my place but it stays cool most of the time.. i have a whirly bird comming out of the attic i could maybe blow a fan out there.. get a portable a/c in the attic or else i need some kind of water chiller where can i find those?

i used to have the plants in bubbleponics but just moved them about 4 days ago into this aeroponics i like it alot more so far.

on my other 2 grows i had this exact same problem come up.. the leafs turn like rusty.. and ive never figured out what is wrong.. maybe the cheap nutes i have are causing it?? i have a ppm reader on order from ebay see how long that takes to get here atleast then i can adjust the nutes better. i really want to know what this is though since its happened on all my grows then when i flowered them it disapeared.

if i turn on my HPS light up in the attic though its going to be HELLA hot up there. last time i had them in the furnace room and thought that was hot.

im sure u can get a water chiller on ebay...
u need to do anything possible as soon as possible.....for right now u can put frozen bottles int the res.....
with temps like that ur def prone to some rootrot issues
and yes u can overdo it.....doing that will lock up other nutes....
u can also use epsom salt to cure mg def

hm kinda looked at ebay what kind of water chiller am i looking for?? they are damn expensive $400+? is there anything else that could work like maybe a PLUG in cooler? that might be tooo cold though since i cant change the coldness in the cooler. it hit 102.8 up there today. wow. and my plants are looking great besides the rusting and all this heat!

If you think thats expensive , think about the electric bill after trying to fight that heat all season long. allways go to coolest spot in house if possible .
