I've got 4 plants, just out of seedling stage (a little over 2 weeks old) in an indoor, soil, grow box with CFLs. They're all in 16oz plastic cups. I was (naively) using miracle grow soil up until today.
Recently (two days ago) one of them started yellowing on it's bottom leaves (it's first, baby leaves), and today it's just gotten worse - they look half dead, and another one of my plants looks like it's starting the same. Is this normal?? The bottom leaves do look like they're not getting much/any light since there's a small canopy of leaves above them and I just today added in mylar. Additionally, today I noticed a yellow tip on the first one's largest leaf :/
Today I also transplanted all of them (into fox farm's ocean forest + some perlite), and all except the smallest one who sprouted late are now looking kind of droopy in their leaves. This is somewhat alarming since previously they'd been very perky looking. I thought I did a good job of not moving the soil or touching the roots much while transplanting ( except for on one of them :/). Also, I gave them a "good" watering after transplanting.
In retrospect I may have been giving them a lot of water previously. I've been trying to let the soil dry out (enough so that the cup felt very light) before watering again, but I found myself watering every to every-other day (I was thoroughly misting them with a spray bottle).
Another thing I was concerned about is that my box is somewhat hot, it's commonly around 85-89 F with full lights, and one day I forgot to turn on all the fans and it went up to around 95 for probably 3-4 hours. NOTABLY the day it got too hot was about a day before I started seeing yellowing on the bottom leaves of the first plant.
Any ideas? I'll see if I can get some pictures.
