Hiyo. Plz notice the 10/30 pics. Should be about 4 more weeks to harvest. I know she is going to start going off as we get closer but this is a couple weeks early for my liking. Any ideas? I water/feed with the basic fox farm trio. With 4 weeks left is it an issue? Thx.

That looks like calcium deficiency. That happened to me on my first diary due to my soft tap water. Your pH is okay so it's not a lockout due wrong pH. There's always the chance it's lockout due to excess nutes but your feed looks fine, unless you are feeding too often? Before rushing to buy any calcium / magnesium additive, I would meassure the EC/PPM of your water, it should be around 0.4 to 0.5 EC (200 to 250 PPM), less than that and there's a very good chance it's calcium deficiency, since it's happening on the newer leaves.

Heyo chef so ill agree with athos on this looking like a calcium issue, its on leaves that are being exposed to the lights which is classic calcium...however a couple other things stood out to me, if youre using water from the tap not bottled ro water theres usually a good amount of calcium available. I also used the fox farm trio and it worked great, however i eventually added a flower booster of theirs similar to what you show, the low N and very high PK and while 2 of my plants further in flowering did well, 1 did not and displayed these similar calcium looking deficiencies even though i was using a calmag supplement. So i later found out that excessive amounts of potassium display almost identical symptoms. Unfortunatey into flowering usually the affected leaves wont recover. But you seem to have many healthy leaves still. I hope you can get to the root of the problem, and definitely check the ec/ppm if you're able like athos mentioned.
Keep up the battle and happy flowering. :v:
