I think I have a fungus but I'm not sure

I trimmed of a bunch of leaves yesterday because they had died. I thought my tent was too hot and didn't have enough ventilation. So I opened the tent turned on a fan raised my lights and lowered the dimmer switch.

Today so woke up and the healthy leaves now have blotchy purple splotches on their leaves like all the ones I had trimmed off.

Here are some pictures.

Is this a fungus or bacteria or what? I couldn't find any pictures that match what this looks like. The first two pictures are before I trimmed yesterday and the last three are from today.

She’s low on Mg. You can see the yellowing between veins. That maybe is causing the other symptoms too. It sure.

Do your grow pots have salt build up from drying out? I am way to new on here to give grow advice but I'm sure if you give more details of your grow experienced people will definitely help you out. They need to know things like what your grow medium is, feeding schedule, water schedule lights, the etc. sorry you're having problems Good luck!

Trimming off affected leaves does no good. As you can see the prob didn't go away, it only transferred to the other leaves. Lets start with what you are feeding them, how much ppm, and how often you feed them.

Something got poured in there. You really need to give some info...you must have 5 threads on 2 continents with no info...just saw the same pics somewhere else ...being vague won't get you anything but more bad advice to follow.

You need to increase duct size and lower fan speed, that gets rid of the freight train sound but you have to have air exchange. Thats besides the point though.
I 'm going with straight nutrient toxicity for this and ignoring the stuff you had going on before. Those leaves are purple because they didn't even have time to change color before they were dead. Are they completely crispy after turning purple and drying? Looks like it.

Okay so,
I started my grow on April 1st. Seedlings were germinated in ffhp in solo cups. After 15 days I transplanted to ffof that I recycled from my last grow. Several days ago when I started to problems I fed my plants with a tsp of cal mag diluted in a cup of water. The problem didn't really get better. The plants are not even theory days old so I'm not sure how they could be nutrient deficient so early on.

I fed them 1 tsp of cal mag only. They were transplanted into ffof on the 15th so I haven't fed them at all yet.

It was not amended but I did add trimmed fan lan leaves from my last grow which had broken down. The soil was has been sitting in a covered bin. I watered the soil couple times to compost the fan leaves. I used bottled nutes my last grow

I haven't fed them at all. They were transplanted on the 15th of April into FFOF so I didn't think I needed to. Plus the soil was taking forever to dry out.

Didn't come back and still not telling anyone he fed it 8.0 ec calmag, leading them in circles.
Folks are guessing heat, venting, CO2 poisoning, bugs, lights, transplant shock or some mystery blight.

From elsewhere on the web from his 5 threads :
"The leaves are crispy and dry and smell like dried cannabis when I open the tent. I wonder if it's possible these symptoms might be from heat stress or possibly a combination of that and gnats."

He's fed it a crapload, raised the lights and left the tent door open so the bugs will leave maybe, problem solved.:idea:
