....Jrock'- This reaction to 24/0 lighting might be related to their strongly sativa lineage,... from what I've seen of others here, often as not this light schedule is problematic and/or not of significant improvement over 20/4,.... your girls did sex out like they should as auto's, but sativa dom. especially seem to do this on occasion; keep in mind that the auto response isn't a fully yes or no thing, but can be variably strong in it's manifestation,... for example, take Sweet Seeds F1 Fast versions of strains that in between fully auto and photo in flowering response,... these still need some sort of drop in light hours, but will react to even small changes,....
Also typical of sativa dom.'s is the leggy growth, which is exaggerated some by the lack of even light distribution in your closet; plants grow toward the strongest light source, so they will stretch and put energy where it's best for them, and cut back where it's weak; lack of reflective material in there makes the light very top biased, and makes for heavy shadowing below, again causing leggy growth,... Tav' is right on the bloom nutes too, at this stage.... I can appreciate your grow space limitations bro' so next round, go with Indica dom. strains, which stay shorter and have less heavy light requirements,... anything you can tack up for reflective material will be a big improvement too...
