Does my conclusion to burnt tips make sense..

So first grow, pure indica super fat scrogged out now i've been noticing yellowing leaves that weren't getting a lot of light because they're so dense

So on the yellowing areas they have blackish/purple leaf edges and tips curling down

I figured the yellowing was burning because they were not creating a lot of energy and using as many resources compared to the areas in full light, so they didnt need that much and the reason they were probably burnt?

pics would help

Pics please. And general info. Medium , lights ,nutes , plant age , etcetera

heres some shitty pictures sorry, phones broken so had to use photobooth

First I must say tip burn smit burn. Ha. I say that because I always feed at dangerous levels thus I always have tip burn at some point during bloom. However I grow monster buds and those burned leaves go in the compost pile.
I think your correct saying low light is the cause of your issues. Or maybe a build up of unused nutrients causing lock.
They show signs of overwatering also. Maybe a good flushing with r.o. Water phed will fix the minor issues you see. They look pretty good to me but you are there with them. When in doubt flush them out. I have never seen a good flushing hurt any plant.

i'm using coco and been watering on the pot weight and its been about every 4-5th day watering you think that too much?

Interesting, yea i think they're doing great needless to say i just want to really maximize the plants potential i wana make some dank stuff that keeps people coming back

they are about 2ish feet, but spread out pretty good through netting, 2 1/2 weeks of flowering using age old Bloom, just started epsom salts, and A.N carboload once each plant

It doesn't sound like you overwater. Maybe the signs of overwatering, drooping I see in your pics are caused by a build up of unused nutrients in your media? But again they don't look bad. I am just a guy hanging out with you in your grow tossing in my .02

indeed it is something to consider thank you
