It's a type of nute burn. Are you measuring your feeding strength? 5 gallon of soil does not need any nutrients for quite some time.

Spots on leavesI'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue.
Still look like PH fluctuation?

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition?
I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Hi all growers, today I did the usual check and after 48 days, I noticed some problems. As you can see from the photos, some leaves have these defects. What could it be? The rest of the plant seems to me to be fine ... what do you think? Thanks to those who will answer me.

Calcium deficiencyI plan on giving a half feeding due to nutrient burn last feed, but with full strength calmag at 1ml/L,
I just want second opinions before it comes to it, Ph has been good the whole time before someone mentions Ph for the 15th time :D
Calcium deficiency or possibly more?
