Alright so I have some Micro Tom tomatoes, sugar baby watermelon, and Minnesota Midget Melon seedlings that are about 2 weeks old. I'm not completely sure how old they are but here are the leaves:
toms have 1 set of true leaves and are workin on their second set.
watermelon has one big and one small true leaves and is workin on a third.
melon has 2 big true leaves and is workin on a third
so my questions are:
when should I start fertilizing them?
what should I fertilize with? (product and numbers also x-x-x)
should I dilute the fertilizer and by how much?
how often should I fertilize?
thanks for all the help

I am puzzled are you gardening in a greenhouse because it should be getting too cold to garden outside in Colorado? Generally I wouldn't fertilize melons, cucumbers, squash, I would just set them out, but if you are gardening under glass then that is a different question.
As for the tomatoes, have you pricked them out (potted them up) and if so into what and did it contain fertilizer and what is the final destination of the tomato plant.
As for fertilizing tomatoes in general, OSU extension recommends that the middle number be much higher than the others something like 6-12-8 or there abouts. If the nitrogen is too high you will get a very large plant at the expense of production. The middle number incourages flowering and the latter better root development in tomatoes. Note that you should also have calcium and probably magnesium in the soil as well to help keep bloosom end rot away. Generally you could add a little gypsom or dolomite calcium (also sometimes called dolomite lime at some places).
If you are potting up in a pot for the tomato, I used as handful of fish meal for the potted one with a T of wood ashes. Some people just use 1/3 compost, both seem to work ok. Other use potting soil that contains fertilizer already, but that is rather high in nitrogen. Note, my fish meal is for farmers and isn't cut it came in at 6-21-8 when they had it analized, I have read that the stuff in the store can be quite different.
By the way Oregon State Extention site has some great articles on growing tomatoes under various condititons. If you go to the site select view for the articles you want to read rather than buying them.
Hope this long winded explaination helps a little

Thanks for the info. As for your questions, yes it would be way too cold to start them outside right now. I'm actually in an apartment and they are growing under my bed. They're under a 4ft light and doing well. I've done this with tomatoes watermelons and cantalopes before but I have never fertilized them. just looking to see if I can get better production then last time.

You can set up your own worm bin if you want as well. Just buy a plastic tote or little rubbermaid container. Add a bunch of newspaper as bedding and use a spray bottle to get it moist. I'd recommend buying atleast 1 lb of red wigglers. They sell them at sporting goods stores but only sell by the dozen and it would be too costly and too much hassle.
You can buy it online. And you just feed the worms kitchen scraps, pretty much whatever you compost. I use them to make worm castings and also occasionally I toss a few to my fish.

Kisal beat me to it, but I was going to say, most potting soil has Miracle Grow (or the equivalent) built in, unless you started with a special seed starting mix. In that case, I wouldn't fertilize at all for at least the first month if not more.
You must have a pretty tall bed if you can grow tomatoes under it!
You said you've done this before, in which case what you're doing must be working. In general it is difficult to get things like tomatoes and melons to set fruit with just ordinary fluorescent light. Light would be the limiting factor here, not fertilizer. In your under the bed set up (great use of the space, by the way!! ), do you have any special lighting (eg metal halide, or sodium lights) ?? Also the tomatoes are self-pollinating, but the melons need the flowers to be pollinated, are you hand pollinating? It would seem like even the midget variety melon plants would take up more space than under a bed... I'm picturing a king size bed on stilts with a ladder up to it to get in and a micro farm under neath... very cool

My tomatoes get to a max height of 10in and both melons don't grow longer than 4ft so I just coil those back and forth beneath the bed. So it's a normal bed thats a normal height above the ground. Also, I'm just using normal 4ft shop lights with flourescent tubes and those work for me. I do hand pollinate them however

I have the micro toms too. But it is my first time growing it. I have a sprout in a 6 inch pot and keep it indoors. It gets sun by the window sill. I also have seeds to both melons you are growing. I almost was not going to grow sugar babies next year because I thought they get too big. I read the vines reach a max of 6 foot.
So I was thinking of a spot to accommodate that. I found a spot, but now you say they get about 4 foot that even makes it better. For the Minnesota midget I plant to grow up a trellis. I would also like to see your set up under the bed. Sounds cool.

Yes, I would fertilize. Ever heard of Miracle Grow? It is great for use in your type of setup with potting soil or peat moss. Of course most potting soils are heavy with peat moss which has no nutritional value. Follow the directions on the package.
I am sorry to disagree with those who say fertilizer makes big plants and no fruit. It has been my pleasure to see that fertilizer makes large plants with more and larger fruit. This on all garden varieties I have grown.

I'm not saying don't use Miracle Grow on your potted plants. I'm saying be sure to check because you most likely are already using it, it is built in to the potting soil. That's probably why you had trouble before, you added MG to soil that was already loaded with it. And seedlings need only a little. If you were fertilizing seedlings that were not in MG soil, you would want to make it no more than half the strength of the directions, probably a bit less. You can easily burn little seedlings or force them to grow faster than than they have resources to handle or set them up to be vulnerable to other problems.

Waterbug,
I've read tons of your posts (my fave was the bees). But yeah, I got a tone of weird looks and the cashier at the local hardware store assumed some things. I joked and tole her "oh yeah!" and then admitted I was growing veggies but I think she still thought I was growing pot. I'm here in Boulder CO and thats HUGE. Tons of people and places get shut down right and left and I'm just waiting for the police to see my apartment's energy usage and then raid and see tomatoes, melons and fruit trees. haha I'd love it

I knew a guy who grew tomatoes indoors, he had really good lights that would take lots of power, well one day ( actually night) the police came, pretty much knocked down his door, asking wheres the drugs, only to find some tomatoes and other veggies. they were pissed and felt like idiots.I'm just waiting for the police to see my apartment's energy usage and then raid and see tomatoes, melons and fruit trees. haha I'd love it

Yeah, but the guy had the last laugh.

alright I just up-potted everything and set up the whole system. here it is under my bed. 5 micro tom tomatoes, 1 sugar baby watermelon and one minnesotta midget melon. also, my beautiful avocado tree that I started from a pit on June 7th, 2011
some images are better than other:

Nice pics man. Hey did you get those Micro toms just recently? I looked through an old thread of mine and you were asking for them, and I linked you to a site. Just wondering if you got them from there. My Micro tom is smaller than yours. But I had a few failed germinations prior. But now I have a pretty good sprout. Its got it first set of true leaves and another coming in.
That avocado is gonna take forever to grow. I started one once from a seed and it got about 2 foot before it died. Another I had just buried a seed in my back yard. And one day I was looking around and found a plant about 1 1/2 foot tall. I tried transplanting but it died.
I wanted to try it again but it takes years before they get any fruit. And from what I hear they need lots of cross pollination or grafts from other trees. But it still is nice to care for a tree/plant and grow it for fun, and down the line you can try to get it to become a fruit bearing tree.

Yeah I got the micro tom seeds about a month ago.. I remember posting in your thread so I probably bought them from the site you gave me. Out of 6 cells each with 1 seed I had 5 cells sprout. so 5/6 germ not bad I'm thinking. those are not very old either. max of probably 3weeks. what was strange was that one of the plants came up and had 3 initial leaves. all the others had a normal 2 but one had a little mutation I guess and caused it to have 3 leaves. all the more photo. for him them lol
