HELP! First time grower:

[Lastwords]

Hello, as the subject says I'm a first time grower. I got some seeds from my cousin and just went at it. Read more than I can handle via the web but it has been a huge help. I just want some reassurance from an expert or two. My plants are 4 weeks old. I have had them in this grow tent from the beginning. I keep the humidity around 60-65%, temp around 68-70 degrees and the lights are on 24/7 (Read either 24 or 18) Been giving them Big Grow 2 times a week. I have struggled with over watering and under watering, sucks I know. I keep a fan blowing in there to make their stems strong. Some of my plants look o-k and others look bad. What recommendations can you give? I will do whatever is in the best interest of my babies lol Also, aren't they really short for being a month old? Thanks for anyone willing to take some time and answer a few questions. Also should I prune away the dead/yellow leaves? Thanks.

Hey Lastwords . Tell us about your soil.

Pic #5 looks very saturated. Yes like @Gingebeard is saying, tell us more about the type of soil.

Gingerbeard and Farmbuck are being very gracious here. I don't know what that slurry is that you seemingly poured over your soil is, but it looks like some kind of mortar or adobe mud. If those were my plants I'd pry that stuff up as quickly as possible and build a house. Oxygen is vitally important to root systems and that stuff isn't going to allow much breathing.

CB, could have been dug up from a yard growing something else? Lots of folks around here have tried it. But just between you and me, I agree. Maybe we shouldn't tell Lastwords to top off the soil/dirt?

[Lastwords]

I took up dirt from back yard, dug a wide hole and put down Happy Frog soil in it. Just to cut down on filling the bags.

all kinds of issue could be lurking it that soil but I digress...need more info on your set up and watering PH levels etc.
