Medium - Coco Perlite 70/30
Strain - OG kush auto
Age - late week 7 from seed flowering Is well underway. Resin just began appearing few days ago.
Watering frequency - minimum 3x a day but most often than not 6x a day.
PH - consistent 5.8-6.0
Input - ppm 500ppm - 650ppm canna coco ab + hygiene pk booster (started this week)
Runoff ppm - Equal to input. (although today I gave 850ppm with increased calcium/Phosphorous and run off still was ~650ppm)
Ambient temps - 8 degrees celsius night time to 20 degrees celsius day time.

Everything was going fairly well apart from an earlier lockout in veg (wasn't watering often enough) but this leaf issue appeared almost overnight about 3 days ago. It appears to be mobile going from bottom to top. Progress seems to be rapid as I just today noticed slight spots starting to appear on some fan leaves at the very top of main cola. From what I've read potential culprits are calcium or phosphorous deficiencies/lockouts. What do you guys think?.

Incase it is in fact a calcium or phosphorous today I upped the nutes to 850ppms by increasing bloom booster for extra P and calcium nitrate. Am I on the right track?

Can we see more of the whole plant?
Hey sorry for the late reply. Yes ill upload a pic of the whole plant if you still want to have a look. But overnight the plant perked up again after upping calcium and pk booster. Not sure which exactly worked but all the topside leaves straightening out seems to indicate it worked.
