We’re on week 5 flowering, I see a couple of leaves looking like this

On first glance what would you say the cause of yellowing is on the outside of the leaves?

Thanks in advance

Thanks mate, over feeding as in too regular? Too much nutrients? Or Too much water at one time?

Tough to say without knowing what you've been doing, but tip and edge burn are consistent with a situation where there's too much salt in the pots, which causes water to flow out of the plants instead of into them, dehydrating the tips, and then the edges. A ppm/EC measurement on your runoff would help confirm if that's the case (or not).

They look similar to mine .

What happened to me was I watered with just Ro water one time till run off . Right after I stared getting yellowing around perimeter of leaves.
About the same timeframe

So in your opinion this could be a lack of nutrients? The only thing it could be lacking is either cal mag or nitrogen but I’ve been microdosing them during the flowering stage with heavy P and K.

My first thought would be too much bloom nutes or too much nitrogen but I don’t believe I’ve gave it too much nitrogen

I believe mine may be a different problem to yours my friend. The tips of my leaves are still fresh looking even though they’re yellow where as you’d has what looks like burnt leaf tips

I had a similar looking problem to yours in my first grow which I believe to be either lack of cal mag or over feeding it.

Looks like too much N is causing K problems. The two are directly related and I see signs of both on your leaves. N needs K to be metabolized and the excess N basically hogs all the K in the plant.

The key here is to reduce N not add K though because that will solve both issues.

Hope this helps and keep us posted!

What makes you think this? I believe it’ll be versed on K

So after being out and about I noticed due to an electrical issue the flowering ladies have had about 24hr darkness 😵‍💫

What will the plants reaction be to this? @Gmix @ArtfulCodger @RootFarmer

Too much darkness isn't a problem in flower. Get it back on schedule and it should be fine.
