So these look alright?

In the midst of my first grow using a top feed drip that drains into a reservoir below. Medium is double stacked 4" rock wool.

Air temp is 78
Reservoir temp is about 74
Feed at 1100ppm
Week 4 of veg
Reservoir ph is 6-6.1

The leaves look a bit wrinkly, just wondering what I might be missing here.

Any assistance here is appreciated. Like I said, first time in this format so I'm just trying to be vigilant

Clawing at the tips is a sign of nute tox. I would back of on the nutes.

Week 4 of veg you'd prob want ppm backed off to 700-800 I don't normally get that high in ppm until flower

Noted, I've added some fresh water to the reservoir to dilute.

Is there a good guide floating around for recommended nute levels at different stages? This is something I've struggled to find.
