Overall plant looks great with beautiful buds developing. Fan leaves are looking fine but she has become dense with skinny, undeveloping, curling leaves.

Please help diagnose.

I'm a newb myself, but from what i've read and seen... Too much nitrogen? Causes the leaves to look like a claw.

that or over watering one

looks like overfert to me. dial your ppms way back and check your pH.

Yep that is Nitrogen toxicity.....flush/ cut way back on the N.

ahhhhhh the CLAWWWWWWWW

I,ve been using bloom fert for 3 weeks, no nitrogen really, only affecting 2 plants, ph is about 6.5. Could very possibly be excessive N from when I was in veg. Will they heal? Should I pull them?

Also just flushed 2 days ago and have only been usin bloom ferts so hopefully no more N problem

Lower you ph to 6.4 and flush them like CRAZY. They will droop really bad for a day but then perk up real nice!
