Sound like a male?

30 plants in a flood table under a 1000 watt hps. They got stressed from a little over fert. One plant looked weird and grew slow then over night it stretched and looks healthy. Compared to the rest it looks a lot different. Shorter broader leaves, less nodes. no pics! ?

possibly, it could be stunted also.

I'm new and inexperienced with hydro so I'm still learning how to feed correctly. hydro is a lot less forgiving then soil is.
