Can anyone tell me what I am doing wrong if my hydroponic lettuce
instantly reaches for the sky instead of bunching?

the only clue I have was to ensure that the nutrient concentration is
increased and consistent, but that "advice" came from the comments of a
caught grower of hydroponic maryjane (as seen on TV recently {:-).

i know a bit about lettuce, but not hydroponics, so my uninformed thoughts
a
1: too much nitrogen?
2: it's too hot & they're not spindly, they're bolting?
3: not enough light?

what is your system like? how does it work? what else do you grow with it?
(very briefly unless it's your favourite subject & you just can't stop ;-)
