Plant dying has been threw alot

Hey I am looking for any advice to save my plant.

My plant is about 1 to 1 1/2 feet tall and has been threw alot.

She was first planted in a friends yard (no soil just what was there) then when she got about a foot tall she started dying so my other friend took her to his house where he put her in a metal bucket in a closet with a long tube light. She was doing better then her leaves started to die again.

Then I took here and now her leaves are dying. Her bottom leaves are turning yellow and black and are dying and her top new leaves are turning yellow. She has yellow and black dots on her good leaves. Most of the leaves are starting to curl up, some are curling up so much it almost looks like it's trying to shade it's self from the sun. I took her 2 days ago. I left it in the same metal pot but gave it new miracle grow soil with 10 % nitrogen. I also have regulated it's water by lowering the ph to around 6.8 I can't leave her inside so she must get her light outside. The temp here is regularly above 100 degree's and I believe that this is why she's dying. Any tips on how i can nurse her back to full health so she can continue to grow outside.

I was thinking about bringing her in for the weekend...any tips on how to nurse her back to health inside would be great.

all that stress might cause it to hermie on you if it already hasnt... you must keep a strict light schedule on your plants or else this will confuse it causing it to possibly hermie and maybe die

I understand the light schedule but how do i keep it from dying if it's not yet strong enough for the outside

Replace the metal pot with anything that isn't metal, let it adjust to it's new soil wihtout blazing direct sunlight on it and water properly and not too often from now on. 100 would never kill a plant that had a chance of surviving to begin with but having no food will and a metal pot sure might. Don't add fert to the soil, mg has enough but do foliar feed and give her foliar epsom salts that way too, she has been starving for a while (could be for any number of reasons).

MG soil may burn her, add any nutes to the soil and it'll kill her but she still needs some foliar feeding anway from the sounds of things and certainly needs magnesium from the epsom salts or calmag pills or something.

And look up how to properly care for a plant in whatever specfic mg soil you have... If it's the full nuted time realease stuff especially.

pictures so i can see what the problem is..i assume its the outside temps..possible using a screen cover to keep it shaded but also it recieves lights if you want to grow it in teh sunlight..maybe using a window instead?
