What are they ? ....Autos or photos.
Looks like you have hit sexing and beginning flower. Did you move to flower cycle ?
The " layering " of soil in your container is not a problem , I have done something similar with a " hotter " mix at bottom.
Plant shock could be an issue , but consistent damp soil can also slow growth and stunt .
Looks like you are in smart pots - keep air circulation going on as this helps move out dead air and replenish .there is no reason also to ( saturate ) pots like those In my 5 gallon smart pots I use a little less than 4 cups water per container and they are fine.
The FFOF should be able to carry the plants BY ITSELF for awhile without ANY NUTES.
Especially since you layered into bottom of pot.
You can insert wooden sticks ( skewers ) to support main stem or any branches that may hang past pot rim. You can do some LST on them too. I used safety pin thru smart pot rim and kite string to carefully OPEN up plant.
Good luck.
