Barneys Farm Mimosa EVO Hydro Problem

Its hard with no diary but that looks like bleaching to me which may be caused by the light if its led.My leaves start to go pale if my temps go below 27c with a lot of light.The led,s lack infrared so the temps need to be higher especially when the lights are strong.90% of what you read about temps refers to growing with HID Lamps.They need very little light at the min.Theres a free phone app to measure light and 500umols is plenty at this stage,300w is more than enough.250w HID lamp is plenty for 1sq metre.Daylight.com has some of best info about growing with leds.
