White widows male or female?

Now there's yellow spots =(

Get a light breeze on those to thicken up the stalks! Get the light a lot closer! And I can't tell sex, but as soon as you see a ball attached to a little rod you know you've got a male. I found that those seem to show sex first

Those containers you transplanted in look a bit large for the stage of growth you're in.

Don't sweat the yellow spots, tho they may be sign that your soil is too hot (too much nutrients) for those seedlings.

Thanks guys. I'm actually beginning to see new healthy leaves forming out of the middle so I think they will be up and healthy in no time. And I'm leaving the greenhouse open from now on to let the hot air out and to also let wind in to strengthen those skinny ass stems.

I had the same problem leftover. My plants had some seriously yellowing and crisping leaves.... I tried everything I could. Adjusted ph, flushed, etc. Looks like they just needed some time to adjust to the new environment, as they are looking much better now.
