What
SoOrbudgal has said holds validity.
Lights are key to successful grows. You may need to invest down the road, but what I will focus on is getting max yield for what you do have.
I have gotten a feed chart. Each column is a new week. (Last column is totals)
These are for your nutrients. (General Hydroponic - basing it on all their products) -- With soil, I assume you are drain to waste (Your not reusing your water) Remember to get at least 20-25% run off through the bottom of the planters. This is also all based on 1 Gallon of water. (If you don't have a pH meter, I recommend getting something you can monitor your pH)

I am going to do this under the assumption they are in fact autos.
Autoflowers will begin to grow flowers as soon as they can regardless of light cycle. They will continue to grow in vegetative at the same time.
You say 13 weeks total (I assume seedling/germ time lasted 2-3 weeks, so safe side we will say 3 weeks seedlings.)
So they would be approx 10 weeks old in Veg/Bloom.
The nutrient line does not separate photo/autos, they provide all a single feed chart.
The first time they start to show any discoloration on leaves, I recommend starting to feed them with nutrients then.
I would then jump to week 2-3 in Bloom nutrients. It will take time for the nutrients in the soil to get used up, by that point assuming they are auto's most of their life cycle will be complete with a bit of time for the final bit of bud development.
I recommend buying a syringe if at all possible to measure nutrients.
Get your 1Gal Bucket (or convert to L) -- Let it sit overnight to evaporate chlorine.
-add 4.03ml of FloraMicro (Drop down to 1/2 dosage when using charts, if you see discoloration, add the full amounts, so long as it isn't nutrient burn!)
-Stir
-add 1.03ml Floragro (1/2 Dose)
-Stir
-add 4.94ml Florabloom (1/2 Dose)
-stir again
-Take pH reading and adjust accordingly to land between 5.5-6.5 (I use 5.8-6.3 myself)
-Feed your plants like normal, ensure at least 20% run off to wash out unwanted salts and old nutrients.
-Wait for soil to dry (When lifted, very little weight, or up to first knuckle is dry)
-Water with plain pHed water (Their chart says after 3 feedings, but I would alternate at least between feedings. Perhaps someone that uses this nutrient line can verify this?)
After that week is done, just work up the next week in the chart!
Hopefully this helps.
As for lights, go to home depot, and see if you can get some bulb splitters . Either get a power bar or a few outlets and get more light in there. With only two bulbs + very small led, you probably wont have much yield when it comes to after the cure. They will be very airy buds. Better yet, if you can afford it invest in at least a 150W set up (Draw from the wall).
A few recommendations for lights that are cheap and work better than bulbs: (Via:Google)
https://www.amazon.com/VIPARSPECTRA..._5?keywords=vipaspectra&qid=1569183900&sr=8-5 (Actual Power Draw: 130W±3% at 120V)
https://indoorgrowingcanada.com/col.../products/powersun-complete-kit-150w-hps-120v (I use one of these for smaller plants, good results thus far)
https://www.amazon.ca/VIVOSUN-Hydro...ocphy=1002115&hvtargid=pla-350110786231&psc=1 (400W light)
Keep in mind, you will always want a larger light. So this would be something you will probably want to reinvest in. HPS will produce more heat and will develop more bud vs an LED, however LEDs have less maintenance cost and save more in power consumption. So there is definitely a balance to be had.
I did look on walmart's website, I have tried several of those listed, and they were all junk. Unless it's a High Pressure Sodium (HPS) or Ceramic Halide (CH) Don't bother with Wally world!
By no means am I trying to get you to buy any one light, just some examples of what to look for. If you have questions, I will gladly help you out (These are without looking at closet size as well keep in mind).
Hope this helps!
Goodluck!
