Hi all I’m new here but have been growing for a while although my growing skills doesn’t show it.. basically I have some plants and last week they were looking so Healthy and lush green growth under a t5 fluorescent light and now only 4 days after I have moved them to different tent and changed to a 720w adjusta watt led on 25% they look so much worse they started to go stiff where as last week they would fully bend when I was doing lst and the leaves just feel quite rough compared to last week. I’m growing in bio buzz light mix with bio grow and alg a mic and my ph seems to be fine. But I’m seriously stressing about it any input would be appreciated

Did the temperature change between the tents? Looking kind of cold.

Yeah I’d say it is a bit colder in there now their in a different room and it’s quite cold outside of the tent.. so maybe I’ll have a look at trying to heat more. I only added the second tube heater just before I took them pics so hopefully might help. Really appreciate your reply thanks
