      Thanks for the response. I’m first time growing. Light I’m using is Phantom DE and about 3-4ft above. And it’s in 7galon pot coco

          I was having the same problem. My humidity was under 20% and I 5hink my light was a bit to close. Im running 2 humidifiers and moved my light a bit and it has fixed my problem. I try to keep my room above 30% humidity

                Never mind I see it's 2 or 3 feet above. How about fans?

                      Photo or auto?
                      What light schedule are you running?
                      What are your temps?
                      Is it on the entire plant?
                      Do you have a full plant pic?

                      It's all bullshit - until you smoke it!

                        Go to the menu on this site and click on plant problems and type in leaf edges curling. It looks like it could be heat stress, root problems or over or under watering

                          Check your plants for broad mites

                            It’s from the new Photo seedling.
                            Temp 26c
                            light 18hrs
                            New and medium grown leaves are curling. Not old fan leaves.

                              It's sure is looking like heat stress (but at 26c), at what height do you take your temp reading?
                              Back off the light distance or dial it down 1/3, if thats's an option.
                              I would go to a 16/8 on/off schedule until resolved, regardless of the cause.
                              If it was roots- the whole plant would do it.

                              I would agree with Weed Pharma, The lower leaves and branches are taking all the water and the topside is drying out because its using more than it can take in. If you touch the leaves and they are dry and a little brittle it's usually from heat stress from lights high temps or under watering. Spray the tops with a light mist if no buds growing and the lights adjusted. Rehydrate the leaves.

                            Temp reading low 19. high27. And lights just dialed down to 825w. See if it help. Gonna check roots later
