Leaves a bit odd..

[anonNoob]

Hello Icmag!

So I have some Heri x Shack in hydro and scrog. Light 150W T-Neon. Everything has went quite fine so far (only a tiny little bit of this same problem has showed up earlier) but now after a week of 12/12 some of the leaves look like this:

They are from lower part of the plant under the scrog (not all have been barbered away yet)
Top is ok.

Bugs? K-deficiency? N-overdose? Help please and karma shall flow!

curling upward means too much nutes, downward means over watering

Weird thing is that the leaves tend to curl kinda where-ever they like. But yea I will try to lower the nutes a bit, someone already said they are sensitive to N but I got scared of bugs...

The lighter green spots in the leaves also had at some leaves some tiny-tiny yellowish spots..
