what did i do to this plant

Northern Lights Autoflower, about 7 weeks into the grow, ~4 weeks from expected harvest.. using 4x 42watt 2700k CFLs (~11,000 lumens)

Its in a mini fridge on my balcony, im guessing its a combination of too high PH water got really alkaline and i wasnt bothered to PH my water after the first few weeks) causing major deficiencies and maybe heat stress (afternoon sun kits the fridge, lights are off but it still got up to >35 degrees a couple days during the heat wave..

couldnt keep humidity over 40% reliably either..

to me this plant looks like EVERYTHING is wrong with it.. pretty much all the fan leaves are dead, all the new growth is straggly as fuck.. barely any trichomes at all.. should i even bother lol... maybe this one should just get put out of its misery?

I have no idea what you mean by frig unit? They look awful. I'm not sure if PH is your problem. But I'm guessing you mean 35 Celsius? That's scorching in Fahrenheit. That could do it by itself. There's not a time I don't check my PH. Slacking doesn't pay dividends. Paying attention and taking good care does. That looks like it's been showing signs of illness for a long time and got no attention when it might have helped. I probably would toss it.

How does she get fresh air? If your growing for experience and something to smoke just finish it off. Put a piece of cardboard or something to help shade her from sunlight.

well don't toss it. It's still cooking or hash material.

i cut out an intake for a 120mm fan

dual 120mm exhaust fans at the top.

to be honest it looked great and was growing like a monster until one day i saw the beginnings of what i now know to be zinc deficiency.. it took me a day or two to figure it out and when i realized my PH was around 8 i started flushing and PHing and got it back to around 6 but its just been getting worse and worse ever since..

this also coincided with the heat wave with several +35C days in a row.

the mini fridge was an experiment and I guess its a failed one.. i will stick to closets lol.. much better results

Flush it through with mild nutes ph adjusted water she should perk back up

i figure shes got 3 weeks left i might as well see what i can do, its all for personal anyway so ill just start a new one and apply the lessons learned

I never toss anything unless its moldy. You can do something with it im sure.

you fucked the ph in the container.
& it wasnt a subtle change.

you can bring that back by staking off , wrapping in clear plastic, & making a humidity tent.

or flush with fresh ph water, raise plant up, and get great airflow over the container.

had a similar problem with seedlings.
grabbed the wrong container for a feed.
did the same thing... but obviously no nugz.

they can come back with attention, low light, humidity dome, and fresh water.

respekt for this very clear response !!!!
slacking never pays.

people dont recognize these plants can be fickle.
but 35c and uber wrong ph... did you in like charles bronson.

ive got a powered intake blowing fresh air right over the top of the pot, under the plant, another 6" fan blowing over the canopy, I already flushed it with a gallon of PH6 water and then gave it 1/4 strength nutes.

runoff is reading at ~ 6.5 so next feeding im going to PH the water to 5.5 to try and bring it a little lower.

some of the leaves seem to be recovering a little bit, but there wont be any new leaf growth this late in the cycle afaik, so im just going to hope for the best.

What are you using for fertilizer. 5.5 is too low for soil. If you're using chemicals then you might have a salt build up. You need a tds meter to check the runoff. If its super high ppms then you know that your plant is locked out. You can get a tds meter for $15.

im using TripTonic Bloom (A & B)

what would "super high" be for PPMs at this point?

Is trip tonic synthetic or is it organic? I don't know anything about the product.
If its synthetic what you would do is mix it up with your water and check the ppms of the solution. Then check the ppms of the runoff and see what the difference is. I would say if its more than a few hundred ppm difference then you need to flush it out until it gets within 200 ppm of what you're putting in. Salt build up will make a plant look like that so will over watering. If you over water and it gets hot your roots will rot. If you lay the plant on its side and try to pop it out of the pot DON'T PULL ON IT grab the bottom of the pot and try to vibrate it out. Take a picture and I will tell you if you have root rot.

7 weeks it should have a solid root mass. If it starts to crumble and fall apart, stop what you are doing and carefully put it back in. I bet its over watering and root rot. Google root rot and look at the images. This is what roots should look like.

I grow organic I don't ph adjust and my tap water 8.1. I only use water the entire time, but I make my own soil. I took this pic maybe two weeks ago. it was getting dark so they look a little droopy.
