Im stumped.. if its user error Im not sure what the cause would be.. my other plants are 3 weeks younger and already bigger in the same soil.. if it was my soil they should have at least vegged properly then showed deficiency in early flower.. They kinda just sat there like a small seedling would sown directly into a 7 gallon container, but never had the typical growth spurt..

Had similar issue with auto purple bastard eater a few years back.. had the seeds replaced and those grew as expected..
Weird.. Mephisto assured me it was my fault though so I guess thats that. lol
