AsNoriuanswered grow question 4 years ago Your humidity is low ( despite it showing 60%) and N on higher levels, feed them with ph water for a week, no nutes, they should start to grow.
Lst always gives small shock.
Hope you do it before watering and no nutes .
Give some love, spray leaves, don't take anything off and just let them grow.
Maybe your light too intence, they don't want to stretch at all ??
