Temp is a question ive asked myself but dont have an answer too. It does get hot ( and i mean hot ) BUT others i know have the same problem with heat with excellent results. BUT i do agree it may be a prob. Its summer here so that aint helping.
Plants do look healthy, no real nutrient sights ( burning on tips, tips curling, etc ). You usually get a rush in growth when turning back with this white widow x big bud didnt grow a millimetre when turned back . ???.
