ok id like to start by saying ive read lots of ur posts n im happy to have u reply to my question. theres no real curling going on besides the folding. the leaves r very dark green but have always been that way kinda look oily too. the plant is pretty deep into flowering at least 9 weeks. i feed it flora bloom by gh. it started at the top but the main reason i think its not heat stress is cuz i had a plant that was closer to the light that had no problems. im growing in ffof. there is a little bit of bron on one top set of leaves but its in like a random spot n the edges r not brown like they would be if it was heat stress.
