6.25 Gallon Pot, Multiple Plants?

Hey, it's been a while, no more AeroGarden, which was a huge success, but this time I'm going Organic Soil. Got a few questions, I have a 25 Quart (6.25 Gallons) pot I picked up from Home Depot, and 3 small pots for the seedlings. I'm going to be using CFL's and a small T5 2 Foot Fluorescent fixture, 4 of the CFL's are 23 Watts (100 Watt Replacement) 2700K for, I'm positive I'm going to require more lighting as the plants get larger and Warmer light (5500k?). The T5 may be of little use but whatever it was 25 bucks. Now I picked up a large bag of Organic Soil, I know I told myself never use Miracle Gro again, never had success using soil (Always Miracle Gro) but it's Organic so I figured why not? Now, my REAL QUESTION, can I plant multiple seedlings In the 6.25 Gallon pot? I was aiming for 3, maybe 2. If not, I'll just get more pots although I would really like 2 plants In one pot if possible. I was going to veg 3 of them until they showed sex, and then plant Fems in the larger pot. Help me out! Thanks!

Tokin' some purple while I get re-adjusted to the forum.

Update: Not usiing that Miracle Gro, It warns to for containers. Oh well, I'll use it for some trees outside. Any soil or other method suggestions?

Elwanna say no but I got 2 plants in a 5 gallon I was told not to do it n yes more lighting as getting bigger I use. 102 Watts 2700k 1 2 foot t5 30 Watt I'm at almost a month on this setup

Do you think I Should just get separate 3-Gallon pots, 1 for each plant? And I'm newish to the soil world kinda, What Soil mix should I get?
