4th week of flowering im getting yellow tips?

[tpc_mikey]

I am in my 4th week of flowering and im starting to see alot of burt tips on my leaves, I am guessing it may be from chlorine in tap water not evaporating off enough before i use it. I have started with pure spring water 2 days ago. any thoughts?

Nute burn...?

What does your meter read here?

I think what you are seeing is the beginning of end of the leaves life cycle. The plants leaves will continue to yellow due to the buds taking all their final nutriments from those leaves, and in 4 more weeks you will see a lot more yellow leaves. It definitely isn't chlorine, as that will only affect the micro-organisms in the root system, as it will kill them which is not good for the roots.
The plants look good, so don't lose your mind over it. Just 4 more weeks, and smoke up.

Good luck

meter? if your asking about the ph i tested the soil and it is in the 6.4 range

Exactly what i keep telling myself its gonna be ok lol, the buds look really healthy. I havent grown in almost 20 years and this is my first attempt back. I dont remember my single bud leafs getting the yellowing last time i grew but im old and may have forgotten. Thanks for imput.

could be over fert also like slyone said, the color of the leaves is very dark green.
p.s if you want to remove chlorine you can drop a little bit of vitamin C (ascorbic acid) in your water, the effect is immediate.

Nute burn...?

You make a valid point as well, I'm currently giving them straight sping water to see if over the next few days this makes a diffrence as well, this was my first thought i over fed them

What I'm leading to believe the plant is extremly dark green when out of the grow lite so i probably over did it a bit right at end of veg, im currently doing striaght spring water for a few days and see if this helps

It's not nitrogen use, this will appear more Autumn-like, the entire leaf with turn a golden yellow, then wilt. What you have looks like high temps and/or a spell where you let it get too dry. When you transition to 12/12, its not uncommon for the plant to suddenly want more water, but only temporarily.

Here are some new photos i took tonite with the lites off so that you all can see the actual color i think its a tad bit of nute burn, i did a gallon flush of spring water will let it get straight water now for the next week or so and see if it gets better.

Tip burn comes into play when the PPM count is to high for the plant,what ever ratio you are feeding with now(or when you found tip burn)can be corrected with a new 1/2 dose feeding.Also do not feed at each watering.In soil feed 1 time per week and use PH plain water in between feeding's

Well I feel like this morning they look a little worse, getting some leaves twisting and yellowing on edges and some have this strange white almost looks like salt building on the edges of the leaves never seen this before. Pics included sorry for taking them under lites.

thats looks like it might be pm starting on your leaves, which is kind of strange, it usually starts on stems and leaves way down in the plant where its shadowed. it doesn't look like an internal problem, it looks like something on the leaves, maybe some kind of fungus. i'd make a pretty strong hydrogen peroxide solution and spray them good with it, see if it has any effect. if it doesn't do anything, then its not pm, but it may be some kind of fungus or maybe even insects, look up scale bugs

 

[Roger A. Shrubber]

i don't think your tip burn and this new thing are related, the tip burn looks like just that, you fed a little heavy once or twice and thats the results. this new thing looks totally unrelated to that

I'm a newby what is pm?

 

[Roger A. Shrubber]

powdery mildew, not a good thing. i'm not sure thats what that is, whatever it is is odd looking, and not natural

Thanks Roger I just got home from work and looked them over again and actually dont see it anymore, I did a few mistings with that spring water i.e. foliar feeding and just wonder if it was something in the water that evaporated on the leaf, it alost looked like salt residue anyways for now its all gone still have the tip burn and those couple of crasy looking leaves but the plant in general is standing up tall and proud so fingers crossed its getting better gonna stick with straight water for rest of week then give it a little bloom fertilizer this weekend. Whats your recomendation on the best bloom ferts? last time i grew i did it straight worm castings so i never had to fertilize.

i've been using vegamatrix, and don't have anything really bad to say about it besides the price. i was reading a few threads and have been trying Jack's dry fertilizer, the citrus blend for veg, and the bloom booster for flower, with calcium nitrate and a little epsom salt. the plants like it, and it cost about 20% of what the old nutes were costing me.
