wow, today marks my 3rd week in flower and i have the same exact plant problem as you, but i am in soil. Strain is Haze x Skunk. Some of my fan leaves tips are curling and looking like a claw. Some of the new growths look to be growing twisted. Some of the leaves are curling downwards like an upsidedown canoe. Not sure what this is either but i posted a message in the plant problem area in hopes of one of the pros to read it.
L3G10N Reviewed by L3G10N on . Week 4 in flowering - Is this normal? I have this plant in hydro. Today marks week 4 in flowering. The leaves are all a nice healthy green and the buds look really good. I changed her solution yesterday. She is using Tiger bloom. Her pH was 6.0 and it is now 5.5. Her leaves are beginning to twist and some are taking a claw like shape. There are two or three fan leaves that have yellow and burnt tips. This is my first hydro grow so I am not sure if this is normal. She still has about 4 more weeks left of flowering. Is this a pH Rating: 5
