Yellow/dying leaves

[H4john]

Hey all, im almost at my 6th week of flowering. One of my plants seems to have an issue. Lots of dying and yellow foliage and now i notice the new growth tips are brown, what should i do?? Is there a way to fix this and is this gunna hurt my final product?

[Deadhead91]

Hey there h4john, few questions what nutrients and how much are you giving it? And what about ph going in or out? And what kind of light and how far away is it?

[Deadhead91]

Also what do the trichomes look like?

[H4john]

They are still mostly glassy, with a few milkys.

What kind of strain are you growing are they autos? What's your pH what kinds of nutes? Some yellowing when the plant is ready is natural. If your sugar leaves are turning brown or yellow then it will still be good just won't look pretty. Maybe a little harshness. How close are your lights what's the temp and humidity? There are some things we need to know before we can address the problem.

Growing feminzed bad azz kush from barneys farm. Using a bloom enhancer, and dutch nutrients flower nutes. Icgive her 2.5 ml of bloom enhancer, and 5 ml of the flower nutes. Also add 1 teaspoon of calmag. Running a 400w hps, with air cooled hood and glass pane. Got it 1 foot above, humidity is low around 30, temps 24 to 25. Ph going in is from 6.5-7, closer to seven will get my run off ph to about 6.5.

Are you in regular soil?

[H4john]

I use a living soil blend 4-4-4

Looks like a potassium deficiency light or nitrogen burn to me. Did you research your strain? Some strains require a lot more potassium. If you use RO or heavily filtered water or overwater you can get a potassium deficiency. But make sure it's not light burn raise your light if you can. The symptoms can look the same. Those look like they're getting really close without looking at trichomes. I would raise my light Idk about the nitrogen in your soil either I wouldn't give anymore nitrogen then what you have in there.

Absolutely agree with you Deadhead91, i have no problems and never feel embarrassed to ask questions even if its simple knowledge to others. Im always reading as well whenever i have the time. Well glad to see you get into this, cannabis is one of the most interesting but beautiful plants out there. The way they look and function is unreal when you compare it to the way other plants grow.

My very favorite part about the plants are the aroma and taste profiles

Not at all trying to be a jerk or saying you're wasting anyone's time. He'll I made the same mistake a few times. Just trying to share the science behind why you shouldn't cut nitrogen too soon. Yes, you don't want too much in your flower at the end, but you also don't want to run out too soon.

[Chefbjy]

Yes deadhead my mistake not nitro burn but deficiency. Still looks like the leaves are curling upwards and could be lighting. If the leaves are hard to pluck it may be light burn if they come off easy will be a deficiency.

[Chefbjy]

Nitrogen deficiency is common late in flower. Sometimes can be a good thing just letting you know she's getting ready. Just watch your sugar leaves if you want pretty nugs.

Thats what i hear once the leaves start turning yellow means its getting closer to being done. This is only one out of two other plants and their doing much better. Just hoping everything turns out ok. Thanks for your help and input its appreciated.
