Is this normal?

my plants just about 6 weeks into flower and iv read everywhere its supposed to use up nitrogen and the leaves change to a yellow color...

welll mine hasnt shown any yet and today it had these little burn marks on the tips of like 3 leaves on the very top om my plant...
is this the start of it using up nitrogen or are these something else?

what nutes do you use? Take a pic of the whole plant.

If your into flower it could be magnesium def-. I have had this problem it starts like what you have and the leafs continue to turn yellow and die. Study up and think about Epsom salts as a cure and preventive next time you reach this point. I have practiced this and it seems to be working. Good luck

This was takin on thursday





ill look into it and read more about deficiancies now lol

don't think it's mag. the edges of the leafs would be fadding.to yellow.

I've never had a plant stay that green. It's looking good. It might just be starting to loose some leafs.

What about chlorine your plant looks great. Is it possible some chlorine got passed through. Just a guess I'm very new to this

chlorine hey?? might be, i really just use tap water lol

lol not if it just started.

Brown tips like that are usually caused by chlorine in your TAP water, and it's no big deal. It happens to a lot of us that use tap water... don't sweat it. It's when your chlorine levels are so high that they are killing the leaves that you have a problem. You have nothing to worry about here.

As for the leaves changing colors.... In general, it's true that they do sometimes change to a more yellow as Nitrogen in not needed by the plant as much as other nutrients during flowering (mostly P and K). But, they don't have to change colors. It's not mandatory. Still, give it a couple more weeks and I bet that you will eventually see some of the fan leaves changing to a light yellow. And that's fine as well.

Your plants look like they are doing great.. Good job.

Also, the suggestion of epsom salt during flowering is a good suggestion. I use it as an additive when I flower my plants and have had great success with it.
