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.

the plants baby leaves. the first roundy ones do die its ok. and put a fan on it os somthing.

i hada similar prob with the lower leaves yellowing and the rest of the plant looking droopy and dejected. my problem was that i wasnt giving them any nutrients. i started the mback on a strong nutrient diet and their MUCH better. the ystill arent 100% but theyre looking healthy, the yellow is giving way ot green and all that. maybe its the nutes

Where they rootbound when you transferred them?

I just learned what that is (last night reading articles looking for similar problems)! I haven't seen many rootbound pictures, but the larger two (the ones with yellowing leaves) DID have lots of roots all around the outside and bottom of the cup. So I would say they were at least a little rootbound. From what I've read/seen though, it seems like rootbound is generally a worse case of what mine were doing.


Update: they're looking less droopy after getting a morning of light

sounds like all around plant stress....um a lack of nutes an overwater seem to be the key..what kind of light are you useing

The only reason I ask that (depending on the size of the plant, and my personal use of the ol' cheap 16 oz cup) is that with it being in such a small container if it has alot of roots it will use up the water in it very fast.

Your problems are connected to poor soil and over-watering and/or pot drainage. Make sure your pot has adequate drainage holes and learn how to water your plants properly. You often get droop after a watering, they'll perk up after a day or so.

Aren't the effects of overwatering usually immediately? 6-12 hours or so?

Go with the pros, like babygro....I still dont' believe a 100%, 90+ degrees in a 16 oz cup I'm thinking overwatering is the least of your worries, even if it was only for a day.
