i'm pretty new to this.when i was young you could throw a seed in dirt and never have a problem and no chemicals were added.i'm in northern ca. my plants are in buckets with miracle grow soil,only the one plant is having this problem,the others only got this very little.they were doing fine untill we had a 4 day spell of 100 degree temps,this is when they started curling and browning,i moved them out of the heat and only the one still has issue's.the leave's are very skinny,curling up,brown and some lower leaves are drooping downward.the tops are still coming out green but not growing very good and look a little deformed.i was told it was over watering so i stopped and in 3 days they began to droop,i watered and they perked right back up.was this maybe the use of miracle grow mix combined with the heat? i'd like to save the bad one if possible,its nearly bud time here and i'm not set up for indoor growing.i hope this is enough information for anyone that can help.what happend to seed dirt water and sun.....please help save this plant....thanks anyone.
