Not sure what these leaves are affected by?

I'm currently 6.5 weeks into flower and one of my plants (kali mist) has started showing funky marks on some fan leaves. I light burned it about 2 weeks back, but have dimmed light and have seen the canopy recovering / getting greener. Last week i noticed these patches started appearing but i can't seem to diagnose the issue - is it related to the light burn? Attached are some photo's - also of the bud itself (Not sure if its behind schedule as well)

From my research, it doesn't look like any of the common deficiencies? I was thinking potentially cal/mag but its more splotches than spots and follows a different pattern to pictures ive seen.

Guidance says kali mist will take 10-12 weeks to mature fully, so i've got at least another 3 weeks and not sure if the plants going to make it? Any ideas?

Some other info:
Temps 25-27c day time, 19-23 night time, humidity keeping it between 40-50% (sometimes goes up to 55%)
Growing in a soilless mix (canna terra pro)
Using a LED 270w light
ph of run-off consistently 5.9-6.1. I keep putting in at 6.2 (as canna recommends) but run off is always lower ph.

looks like some kind of disease. if it's only one plant out of a few or more in a tent, it's probably a disease.

Looks like she could use some Calcium.

in my opinion the plant looks starved to death and usually they get worse and worse pretty quick what ppm are you feeding and what are you feeding?

I'm only growing 2 plants, so not much of a sample size. Other one had a calcium deficiency but it looks much different to this and in line with pics of cal deficiency i coud find



I'm only growing 2 plants and my other one had a calcium deficiency (though it looked exactly like pictures i could find on the net) - can different plants have different signatures for the same deficiency?


Yep this happened a few weeks back so scaled back on the nutes - have read Kali Mist doesn't like a heavy feed.




See above comment - i might have gone the other way too hard now? I'm using the canna range of nutes (+cal-mag supplement now) and following their guidelines to about 70% with 1.3 EC atm, going a water-nute-water-nute feed cycle. (previously nute-nute-water)

Well I had my last grow do the same shit wasn't sure if it was lockout or deficient or what so I flushed then added nutes but the girls never recovered and limped into harvest with zero leaves left and never got ripe

Orange, punctate rust spots are signs of a Ca deficiency
