I would recommend getting superthrive or another vitamin b supplement for plants when you transplant them
Good advice freehugs, most liquid plant food has vitamin B complexes as well as other important nutrient profiles. Bigga Buds is a great aussie plant food and bloom booster that has B vitamines, Potassium, Magnesium etc and added bee's wax and honey! Think the honey both acts as a disinfectant and as a ready supply of dextrose, not sure about the dissolved wax though?? I used to use "Iguana" a Canadian companies organic liquid plant food along with "Piranha" from the same group Mycorrhizas benifical fungi.
A bit on mycorrhizas from wiki: "Endomycorrhizas are variable and have been further classified as arbuscular, ericoid, arbutoid, monotropoid, and orchid mycorrhizas.[26] Arbuscular mycorrhizas, or AM (formerly known as vesicular-arbuscular mycorrhizas, or VAM), are mycorrhizas whose hyphae enter into the plant cells, producing structures that are either balloon-like (vesicles) or dichotomously branching invaginations (arbuscules). The fungal hyphae do not in fact penetrate the protoplast (i.e. the interior of the cell), but invaginate the cell membrane. The structure of the arbuscules greatly increases the contact surface area between the hypha and the cell cytoplasm to facilitate the transfer of nutrients between them." wiki. These fungi can create a root area 100 x larger and more efficient than control plants with no mycorrhiza present. The bigger the root system the more food the plant can absorb and the bigger the plant will grow and the denser the buds!!
As for the seedling don't stress at 11 days it'll be fairly small if your using an 80 watt bulb (different story if it's a 400 watt on a 18 hour cycle

)and will only have a small root system. The fact the soil fell away means the plant has not developed a very extensive root system. You should have no problems at all. A little stress makes the dope stronger at the end of the day, too much stress will kill though. As freehugs has stated severing the tap root will cause problems like death of seedling due to stress, infection. Have you ever used the green foam like hydroponic substrate for raising seedlings? It works well and the only issue I ever had was drying out of the seedlings under light as I'd neglected to program a mid cycle water of the seedlings and they were crispy critters when I checked the grow cupboard

.
That said I visited my brother and he has a few little mullies on the go. They sound about the same stage as yours drug_mentor. He's grown dope for almost 20 years and just does the minimum of fussing especially when they are seedlings. He usually plants 15 or so in case some die (seedlings are a bit prone to this lol), turn male or transgender (male and female sex organs on the plant aarrrghhh I hate that!). He really just does the bare minimum and he still gets chronic bud. He does put more effort into them once they start to mature and even more once they bloom. He uses a similar fertilizer regime to the one I have outlined in my previous post (except he uses a watering can every few days with nutrients added) with a H20 flush 10 days prior to harvest.
When did you water them last? If it's standard soil it'll retain the moisture more than well draining soil/substrate. This may result in root rot but if you watered them yesterday and their is only moisture at the base of the pot it should be fine. I always have had issues growing seedlings using standard soil or potting mix as I usually get root rot. After changing to high drainage sterile substrates this issue became null.
A little about root rot from wiki: Many cases of root rot are caused by members of the water mould genus Phytophthora. Perhaps the most aggressive is P. cinnamomi. Spores from root rot causing agents do contaminate other plants, but the rot cannot take hold unless there is adequate moisture. Spores are not only airborne, but are also carried by insects and other arthropods in the soil.
A plant with root rot will not normally survive, but can often be propagated so it will not be lost completely. Plants with root rot should be removed and destroyed. Excessive moisture reduces the ability of aerobic bacteria and fungi to maintain a healthy micro environment. Aerobic bacteria and fungi such as mycorrhiza out compete the harmful bacteria if the soil is well drained and oxygenated.
