Moved indoor for veg...... and now it wants to die..

O i started a little clone outdoors it was happy healthy, along with my seedlings.i pulled the seedlings out from th light and they stopped dying... Now it seems to be dying from inside out my led light is about 18" away from the canopy on her however i dont think this is a neutriant defficiency, this is somethign to do with light? plenty of air circulation, it got a little warmer than id like for them the last few days but its been hotter outside for my girls and they did jsut fine.

i have her on 18hours on 6 off and she is dying the lower leaves, and this is happing quickly...like over night quickly .. one night...

my outdoor strains (same kind) are getting ready for blooom but are still very happy

what am i doing wrong with this light?
