4 weeks - feedback, tips, help NEEDED

organic soil mixed with compost
watered when soil is dry 2 inches deep
outside in greenhouse with possibility of moving indoor
the bigger one started to get yellowiing on one of its leaves but it net away after about a week
I don't have a fan blowing on them so stalks are a little thin, but other than that they just look weird to me.

Help me out fellow stoners!

Your pots seem inadequate, where are your drain trays and drainage holes? Can you get any airflow to the greenhouse, or a fan for movement?

They are stretching due to not enough light

Not enough light was my first thought. And if there is no drainage, time to whip out the power drill.

Pretty crazy though, 4 weeks in veg and still has its catelydons..lol
