Brown patches on leaves

Got some brown patches on one of my plants leaves 32 says into flower looks like nutrient burn but other than a few leaves with little patches already checked if rust fungus it's not should I stop feeding nutrients for a water or will that starve the plants

check your ph meter, calibrate it regularly. Mine f ed up leaves all purple and necro spots from 2.4 ph 3.4 ph when meter read 5.4 to 6.4 makes a big difference.

My soil ph is fine plants look very healthy patches just on 2 buds and both are the highest and closest to the light was gonna turn down slightly but didn't want to lose light power as well into flower if I turn down slightly would that have a drastic effect

Not on the buds themselves just the fan leaves right at the top

If the top buds aren't affected just fan leaves is the light your issue. Pics and a little more info would help

Think I is the light as it's just the leaves closest to the light was worried if I turned down it would affect my yeild have to water today was wondering if I should just give water with no nutes sent pictures of other plants too they look okay ?

I assume your out of height to raise light can you train them down any. Look decent but imo looks like a lot of N for flowering but I wouldn't stop feeding completely

Branch way too thick to train now unfortunately no space and what do you mean too much N for flowering? Should I try half what they been getting I have changed to flowering nutrients completely now and I just started using PK booster for the recommended 4 weeks was think it was the.cal-mag ?
Sorry for going on always stoned so many thoughts at once lol

Tbh it doesn't really look like light burn to me...could be, but hard to tell, maybe give those deficiency/excess charts a look. Given that stuff looks pretty healthy overall I wouldn't worry too much. The leaf edges make me think deficiency, but it could just be that some moisture got on those leaves and left weird spots.

Would concur that cutting your N levels would be good. Not sure if it's a settled issue, but many believe you get better flavor and a better product overall by limiting the amount of N in flower. Your plants are kind of a dark green color indicating high N levels, some shoot for an overall lighter color.

Calmag does have a pretty decent amount of N.
