Humidity or Nutrient problem?

First feeding - where I messed up I think - 5.6 pH - 1.1 EC - 545 ppm
Second feeding ( right before pictures today ) - 6.1 pH - 0.6 EC - 314 ppm

It's supposed to get REALLY humid the next few days and I noticed my tent went from a normal 52-55% to 60-62%. Is the drooping of the leaves because of my over feeding, or because of the humidity, or both?

What soil you got?

Pure Coco aside from the peat pellets they started in.

They look fine. They get droopy after waterings. They should spring up shortly. If not add more info and maybe someone can help

They were like that before the watering is what I was getting at and does high humidity do that to the plants or is it mainly because of too much nutrients?

How often do you water?

Put mg in water? No perlite?

Every 2 - 3 days, I wait for the soil to get dry then water. I added CalMag first feed. Not the second. Was worried about burn.

Over feeding and Coco binding the mg. Lack of oxygen in root zone, look young for feeding bi-daily anyway. Always add mg to coco.

Feed, water, feed.

Are you misting them. Don't worry about humidity with seedling they love moisture. I would mist with a mild mix of liquid karma or something similar

Looks way overfed to me too.
0.2ec would be plenty right now.
