FIRST OF ALL: i have never used aeroponics, and do not properly understand its mechanisms.

in soil though, nutrients are reserved until the plant is of suitable age and hieght. this may not be so in aeroponics, but i would still suggest using the most minimal nutrient concentrations until it becomes bigger and stronger.

second, i do not see any apparant burns or wilt? the plant appears to be thriving in its conditions.

what lighting is it in? and what strain is it?
