in need of desperate help

i have 4 potted plants, it was too hot during the day temp reaching 116F in my tent with the light only at 50% (300watts) so i decided to operate at night when its cooler, when i turned it on the humidy was 61% and the temp was 73% when i woke up this morning the temp was 85% with a humidity of 33%, way better temps than what i was running in the day i think, but i woke up this morning and this is what i got. any idea's to whats going wrong? too much water? not enough water? i will say when i got up this morning n checked them out widow soil was really really dry. so im thinkin maybe it was thirst? from 9pm to 12am the light is on and from 12am to 9pm its off, but anyway heres the pics, sumone please tell me what im doing wrong. when i went to bed white widow was looking good, now in one night she look like shes wilting and dying white skunk doesnt seem effected at all lol wonder woman ill prolly pluck, shes had too much time and not doing well, bubblelicious might survive if i play my cards right, any help and suggestions would be appreciated.

no comments or suggestions?? come on guys, im told yall are the best, uncle ben help me out lol

Damn man i feel bad for you.. I wish i could help you out but im new to growing...

I think they got crisped a bit. If your temps stay lower, they should recover. If you're feeding at all, stop for now ... mild nute burn could be additive. cn

Yeah they look a little burned up from over feeding , cooler temps would be beneficial for sure.

I just realized ... you have the light on for three hours a day. That's not good. cn

no 15 hours on, 9 hours off, ill be checking in on them and watching carefully, thx for the advice guys also would it be wise to clip the dead leaves off?

Only clip the leaves that are over 50% damaged. No need to do it right away either. Wait til you see new growth.

This looks like some kind of nute problems and heat damage... 115F is VERY hot for a mj plant, they almost stop growing once it hits the 90s... 115F can kill them AFAIK.

Flush the soil and give em fresh nutes and see if that helps. Till then keep those temps below 90F, that's really the upper limit of what the plant can work with. Best to keep it in the 60s or 70s though (lower is better because it drastically slows the growth of pests).

Another reason light as high up as possible!!! let plant's grow into their space...harden off under 600 and pump!!Get ac take care of problem put on floor in pan for condensation (LITTLE) back end facing window with it open.... make it easy what about next time ??Had three day's of heat boston...more comming!Why kill the plant's with the one thing they need light=heat????!

see the reason im turning the light on at night is to keep it cool, i got 5 fans blowing around air in the tent and a fan in the window of the room and its still 100+F lol and currently lack funds for a portable a/c unit, but i noticed with what im doing the highest temp was 88F with a humidity of 40+ when i turn the light on during the day, 100+ and humidity of 22-25% but i agree with nute burn, im using iguana grow and i think i might have over did it, but im just give it straight water and flushem and just be patient and hope for the best, i will clip leaves later on, widow has a ton of new growth, so ill go pruning l8er and post pics after a few days, but as far as i can see the only way to cool this thing down is to get the portable a/c unit wich i will get eventually, or do the night time thing.

i bow to you sandie, awesome set up, but ill do what u say and crank the light to the max, its only at 50% right now, but only after i get the a/c unit lol im too afraid to do it now, might burn up my babies even more

and the way that shit looks id travel for it lol

Basic ghetto grow but slow and steady! Your's will look as nice! just pay attention and do what work's for you! Most people grow much different but i'm old 62 and work smart not hard... no moving shit around set it and sit back and watch that's all you need to do if it's a good workable set up! I only visit when I can not daily..home taking care of wife doing this due to age..people wan't to sell me shit by the gram!! fuck that I've grown lb's my whole life just outside instead..easier inside you have all the controll!! jack

exactly seasons and sun dont mean anything lol why i went with the indoor grow, and i hope everything is alright and i hope for the best for your wife. i recently started the night time op because of the heat and lack of 200 bucks for a portable a/c lol but i think my main prob was over nuteing. at night the heat doesnt reach past 88% and the humidty past 40%. so ima stick with it, in the day when the light is off it is in the 70's for temp and 50-60% and the skunk seems to like it, and i fear if i turn the light on during the day the heat will just fry them lol and i agree, fuck paying buy the gram, i dont have that kind of cash lol i just want to have my own personal stash

Um I believe thats neut burn my cannabis growing friend.....and my god you have allot of it :O

bro, you need to fix the environment.... 100F temp way to high, looks like ur in a tent, how you have your intake exhaust set up?

yes jack help me confirm nute burn lol and yes there was alot of it, and i know 100F is too high, thats why i switched to turning the light on at night, it never passes 88F, so thats taken care of mostly, as for exhaust, i got inline fans and circluar fans everywhere lol blowing out the tent, in the tent, on the light, the plants, the ballastic lol im trying to keep everything cool, but im in a trailer and it seems impossible during the day, so i switched it up to where i dont flick it on till about 9-10 pm then around 12-1pm next day ill shut it off pretty much 15 on and 9 off, ty all for the comments and suggestions, much appreciated

WIKI>>>>>>You said one thing that threw up a red flag!!! Fan on light>>>>>>if you do this you just spread that heat out if you move fan to blow past it to the top where it can be exhausted you might be better-off! Just a thought...didn't mean to be condesending my friend I'm sorry just sometim's the word's come out too fast!! I like your reaction to the situation and only wanted to help if I could! Wishing you only the best!! jack
