Moist build up at bottom - overwatered
I believe this seedling had too much moist. The soil was moisty when I filled the pot. Somehow the pot feels very heavy now and seems there is a build up at the bottom. I made some airpockets to the bottom. Should I wait or take it out and put it into a cup and dry the soil?

Nutrient Burn/Lack of Flushing
I misunderstood the flushing process early on (thankfully my growing medium is light) and didn't flush the medium with 2-3 times the volume of water. It was more like a 1:1, maybe less. Is it too late to flush now without drowning her? Soil is fairly dry at the moment.

By looking at the pics does anyone have an idea what's up? This started 2 weeks ago after a suspected low Ph watering with (FF Big Bloom) but I'm new so not sure. First I flushed her then over the last 2 weeks have given her some CalMag+, Molasses, FF Grow Big, and Epsom salt

Brownish Spots on 2 Older Leafs. Young plant.
I searched it up before posting this and what I found is: Leaf spot, canker, and fungus: Brown leaf spot, Yellow leaf spot, Cladosporium stem canker and Chaetomium fungus. Solutions I found in the comments below. What do you guys think? Can it be heat (a lot of hot days here)?

Have popped 2 seeds, 1st week of grow. One plant started to roll down her leaves extremely right after losing the shell. Anyone knows why? What to do? Had extreme dry RH in first days, it dropped down to 36% sometimes. Both plants have root fungus in substrate. Thanks!
