Hi growers!
Day 45 on a grow of Jack Herrer, and I had several leaves looking like this when I went in to trim her up last night. What can I do to correct this?

Thanks in advance!

Check your ph, it does look like a cal/mag issue, but start with ph.

Lookin like the beginning stages of lock out. Get revive by advanced nutrients, it will help greatly.
