Brownish reddish spots on leaves and dont know why help please!!!

Hi im growing a durban poison plant she is in her 3rd week of flowering and over the past 3 or 4 days i have started to notice the bottom outer fan leaves are begining to get these reddish brown spots. I flushed the plant its first week into flowering and only feed it nutrients every other water or as needed for certain nutrients and the spots arent on any of the new leaves coming out. about 2 weeks ago i gave the plant a foliar spray but mistakenly did it with water containing nutrients in it...now i dont know if that had anything to do with it since the other plants i mistakenly did that too also have no spot. i am using mylar to reflect the light could this be an issue too? i have sufficient ventilation and my room temp is usually around 30-32c and my humidity never goes below 40% or above 60% i will try to get pics up asap in the mean time if there are any suggestions as to why this is happening and how to spot it would be much appreciated

1st I nver foliar feed or water during flower...causes mold. Secondly from your description I am thinking a Mg deficiency. Get some cal/mag or magical or ven epsom salts at 1/4 teaspoon per gallon of water. Should help, good luck!

I've just had the same problem, started Cal/Mag last Friday, no noticeable difference yet.

also be careful not to have drops of sweat fall off your body onto your plants , it does the spots too. It happens sometimes and you don.t even know you're sweating.

i dont have cal mag around but i do have grow formulka with mg in it could i use that to suffice til i get cal mag

you need calmag plus for flower i think botanicare is the best. your ph could be off also that could cause the lockout issue

All your problems are from the temps being 32 deg which is far too hot , reduce the temps to 25 and watch the plants improve.

shopuld i still try the cal mag or reduce temp first to see if that helps its kinda hard to reduce the temp cuz its a small room i got a fan towards my plant to keep the plant its self cool plus i got an inline duct fan right near my hps light sucking all the hot air out

plus the only leaves that have the spots are the outer leaves the ones that are in the most heat the ones in the direct light dont have spots at all so i dunno if it would be heat i have mylar in mny room tho you think it could be that

sorry for being such a burden i really dont wanna loose this plant i grew from seed and 3 out of the 4 plants i put in bloom were male so shes all i got haha

now this isnt my plant i actually got this pic off the net cuz i dont have a digital camera to take a photo but ill post a pic of what it looks like only its on like 10 leaves toward the bottom outeer portion of my plant and the leaves that have it are a very dull pale green all the other leaves are normal

lol also if theres any suggestions of easy ways to reduce temp in a closet setting that woud be helpful too. ive had my card for 2 years now and this is the first time ive done a closet grow im slowly building my main room in the basement but until thats finished i am stuck with what i got ill post pics by tomorrow for feedback and constructive critism and some pointer thanks for all the help guys
