3 Blade Leafs & 2 Spontaneous Auto's.......

Got a question or three for you experienced bastards out there. This is my first grow. Started out with two bagseed plants and a Purple Widow. I can't say for certain the two bagseed plants are from the same batch.... but I can't remember getting a seedy batch of weed except for the batch I got the bagseed from. First off the two baggers are as different as they can be. If they are from the same mother plant,as I think they are, then I'd guess it to be a random cross. That doesn't bother me though. What gets me weird is one of the baggie plants and the purple widow (a male) auto-flowered in a 20/4 light schedule. My first question is can you auto a plant through environmental stress??? My wife cares for the "kids" when I am gone. But at a bare minimum and this my last time at work she mistook "misting" them everyday with fucking drenching them with a full watering everyday. They are bouncing back from the damping off and subsequent cal/mag lockout. The PW male was in coco.... so I her "oops" didn't fuck it up like it did my two in soil. One of the baggie plants is robust, very "pot" looking leaves... healthy and seeking the light. The one that autoed (female... yay) is a runt looking squat, 3 bladed damned near purple leaf oddball..... and kicking up something like 17 hairy buds on a regular veg light schedule while being the size of a large grapefruit. Also, the clone I took off the oddball auto bag plant budded as well..... in the cloning chamber!!!!!! Oh, and this bitch had normal leaves for 4 weeks and then ditched them for all 3 blade leaves...... I don't have any super specific questions... just a shitload of curiosity.

1) Can the auto trait be induced by fucked up conditions?
**only reason I ask this is because the male PW autoed as well. It may have been a genetic thing. But I want to rule out environmental.

2) Can you get a mix of auto and non-auto seed out of a single female?
3) WTF is up with 3 blade leaves??

I really wish someone had giving some input on this one. I have the same thing going on, flowered under 24, been 12/12 for 18 days now and half the trichs are cloudy and the things like 12 inches tall and loaded down. All the new leaves on the lower branches are three leaves. Sorry to revive a old thread but Im curious as to if the plant has lowrider genetics or if was something environmental. Right now they are in a cabinate with 292 watts cfl mostly 2700k but with a few extra 6500k.
