yellowing tips

almost 2 months flowering now...i know near the end of flowering plants turn fall colours and such...just wondering if its normal or something im doing wrong

i started feeding only water to flush the chemicals out about 3 days ago so i know its not nute burn...wondering if its a deficiency of some sort possibly?

any help is appreciated thanks

thought i'd throw a close up in there, i know how crystals make me drool

Looks like nute burn, yellowing of the fan leaves is normal in the flower room. the buds are feeding from them

As far along as you are it's completely normal. While flushing at the end almost all the leaves should start to yellow and die off. Like Rbregn said. The buds are just sucking the last bit of nutrients out of the fan leaves before it's ripe. Congrats man looks good!

I have seen clorine & superthrive cause that type of burn and also heat from lights (leaf tip touching cfl)

I'm a keep em green grower so disagree that it is "NORMAL" to turn yellow at the end, but most will tell you it is

it hasnt had any nutes for 3 or 4 days...so its no type of nute burn, and the lights have never touched the leaf tips, thnx for the input, but thanks for the input

It is clearly the begenning of a nutrient burn. you probly over-fed during the last few weeks of flower. It doesnt show damage right away, if you are seeing it now, it is from a couple of days ago. Now that you're flushing, the problem should stop unless you have a serious salt buldup problem in your soil. If thats the case, you are still feeding the plant. I would do a soil flush, let it dry and water only until harves. If you are unfamiliar with soil flushing, you run water through the soil until it comes out clear. The yellow you will see coming out is the salts, and thats a good thing. Usually you need to run at least 3x as much water than the volume of the soil. so if you have 3 gallons of soil, you want to run at least 9 gallons of water through it.

So you know why I am so sure its a nutrient burn, it is of course the way it actually looks, brown tips fading to yellow, but it is more because it is on the buds themselves. If it were a deficiancy, it would start by the the bottom leaves yellowing only, no brown, and slowly progess up the plant untill there were nothing but buds left, then they would start to show it.
