Wtf moment: need help

[Lildaddy]

Hi, fellas,
I’ve just finished watering my plants with a lil bit of green hpuse grow powder, melassa and a bit of superthrive. all of a sudden one of my plants went into shock (picture), none of the other plants have such symptoms.
1. I thought it may be overwatering, although i thought it was too quick to be that, dug out a bit of soil and it was not overwTering
2. There was no significant change in temp, moisture, airflow conditions.
3. From what i read online i suspect it may be nitrogen surplus, however the plant did not show any signs ot anything unhealthy, it was 100% good.
4. Since i water mainly on the endges of the pot, i also thought it may be underwatering ( it was 4 days since last watering) i put some water directly nearby the stem, like 30 min ago and it still does not show any signs of getting better
I would appreciate any advice
Thank you

If they don't perk up after watering then it might not be underwatering, your first assessment may be correct, nitrogen toxicity.

Is it soil? Is that the first thing you gave it in 4 days? Do you ever water first and then follow up with the additive? In those pots you can soak till there is runoff. 30 minutes isn't really enough time for the plant to regain turgor rigidity, so maybe look back in a few hours.
