what's wrong with this leaf? Ragged holes!

Hi all..

I'm looking for advice on what the problem is with this leaf.
I haven't seen many with this issue but would like to know what steps to take to correct it as its probably a warning sign.
This particular leaf vane from the bottom of my 2ft blue dream.

grown in hydro with constant nutes

ph 5.5 to 6.5, likes to stay above 6


ppm 900 or so, sometimes over 1k

feeding cal mag botanicare and general hydro starter kit

hydroton medium with solution spraying the roots every 15 min

all indoor, 70 to 80 deg, 40 to 60% humidity

some leaves show burnt areas but they might be touching the lights at times.

T5 lighting only

I don't see an option to attach a pic using my phone so I'll figure it out and attach a pic asap hopefully.


Thank you!

Is it just the one or several of them.could be nuts burn or bugs of somekind check out the bottom of the leaves. My zipper on my tent sometimes rips the leaves when I unzip it, but I never have any burn. If you check out the leave right in the middle in this pic you can see the leave my zipper has ripped.
