New Grow, Twisted leaf.

Was wondering if anyone could tell me why a couple leaves have twisted fingers almost ?
I've only noticed this on maybe three plants only one leaf per plant as well. Also the second question i had was whats the deal with this plant and a couple dead looking tips.(should be second picture)

Hopefully the last picture is a group photo if y'all could give me any pointers or just keep doing what im doing with my first grow.

Some info: All of them are Super Silver haze besides one OG.
they are in 1 gallon pots right now, but I'm about to transplant them into 5 gallon.
I'm using Fox Farm Ocean Forest soil. I have FF trio for nutes, but i haven't even messed with them yet really. wanted to get the hang of just using water only really lol.
I have them on 24h light right now under what I think is a 500w LPS. I have two 1000w HPS for vegging though.

Well the twisted leaves are usually a ph problem which alot of people have been having with ffof lately. You should add dolomite lime into soil. The dead tips are the beginning of slight nute burn from the ffof being slightly hot for young plants. They seem to be handling it ok I wouldnt add any nutes for awhile yet.
