Yes, less nuits and more water. Do you have a PH pen, if so you should check and see if it's right. You will still get a good harvest no matter what, you have decent buds already, but it's now that they swell, to many nuits, and your plants will slow down, get it just right, and they will burst out of your tent. I've grown plants that have sucked the fan leaves clean in week five, and still got a good harvest, but I can't help thinking it would have been better if I had gone a little more steady with the nuits.

I have 2 ph pens and 2 ppm pens. Have not calibrated though. I will check all that when i get home. Thank you for the help.

Sorry, ph has gone tits up? At 6.0-6.1? Is that to high? How do i lower ppms? Less nutes/more water?

I was thinking that if they were more Sativa they would burn at a lower PPM, but 30% is not a lot really. Might still be the cause if the others are ok.

I've seen it a million times bro, your plants are a little nitrogen starved. I got purple strains in my garden right now that started doing the exact same thing yours is, don't cut out veg nutes till final flush. 50\50 bloom veg ratio till around week 5, then go to about 60/40 bloom veg till flush. Your ph is fine, you'd see ph fluctuations symptoms on the leaves like blotches and shit. You got uniform color changing pretty early in bloom and the plant looks a little oxygen deprived, and If you haven't been over watering then nitrogen deficiency can make your leaves droop. And like I said before never water till excessively run off unless your plants is showing problems, all your doing is leaching the medium with run off. My purple strains are doing the exact same thing yours is doing but I controlled it and made it happen in final flush, yours are taking on a flushed look way to early in bloom and will cost you if you don't get her back on track soon

The other dudes are right, your showing signs of np and k deficiency but it's all stemming from the lack of N. Give your girl a good 50 50 ration at least a nice teaspoon or more each watering of veg nutes and your bloom nutes until flush she'll be back running full tilt in a week.
I feed my plants veg and bloom almost every watering and my plants stay beautiful through the whole cycle and stress free and yield at full capacity. The bloom cycle isn't very long in truth so any stress or set backs cost you on yield.
As for all that ppm meters and crap, really only good for metering amended medium, gives you an idea of the nutrient content of medium as amendments break down, if your using liquid nutes then you know what your putting in and the plant will tell you everything you need to know. Ph fluctuation is almost the easiest to spot, most mediums are pre buffered, if the medium sways it fluctuates back to where the buffer has the range set and comes with blotches, crispy leaves, burn, all kinds of crap.

Why wait for a PH fluctuation when you can keep it on track with a meter, when I bought my first PH and PPM pens I thought they were a gimmick, but I can tell you now, using them produced far better plants than winging it, that's a fact, even more so when I moved to DWC.

I got a couple of them and only use them when I flush my my plants, so if I want to do a slow flush then I know how much to leach out the medium, other than that I've found them to be quite useless. It's really only reading the microorganisms that are in the medium, not necessarily the nutrient levels. Don't need all that crap unless your using soil amendments otherwise you know what your putting in your medium. You can meter your run off and then come back an hour later and it's totally different. Isn't like the ppm meter tells you "your short on phosphorus", only tells you there's a lot of life in the soil and the more life in the soil means more microorganisms shit witch is what the plants eat. Ppm meter has nothing to do with ph, you got to have a ph meter and it's a lot more important to adjust what's going in because your soil is buffered anyway, you try to adjust so you don't fluctuate.

@KlipschGuy, how do you like those speakers. Im assuming your name of course. What nutrients do you like? I have read so much on all the nutrients and have come to the conclusion that the best nutrients are preference and comfotability. You have good taste is sound so you arent an idiot lol. I didnt get any veg nutrients yet due to soil being pre loaded.

Google.... yellow leaves purple stems Marijuana deficiency

So phosphorus and the cold huh? While we are here. Im noticing all the fan leaves on all the plants have purple stems but healthy leaves. Same problem maybe if even a problem at all?

Again, thank you everyone involved with this post. I really do appreciate it oh so much. Helping me learn my shit will help me perfect this craft and give me the ability to share this info with people also needing help. The one problem i have with growing cannabis so far is it doesnt take up 90% of my time lol. One more time thanks all you, you beautiful people.

Thats probably just genetics bro, some plants turn purple without cold temps. All cannabis is purple underneath the green pigment, you can force any cannabis plant to turn purple but breeders have figured out how to turn cannabis purple naturally through breeding. Nitrogen deficiency can come in many forms, pale plants, uniform even yellowing on just a few leaves, nitrogen is the base nutrient and if it becomes scarce the plant will run out of energy and make all other elements immobile. The old rule was to shy away from nitrogen in bloom but there's new evidence that's says just the opposite. You don't want so much nitrogen that your leaves are clawing and shit but you want a nice regimen throughout bloom.

I'm wouldn't buy a different brand of audio. I use gh flora nova and sweeten my soil less mix with organic amendments

I know for a fact that if I cut veg nutes out at beginning of bloom, my plants look weak, strange deficiencies pop up, all around ruin your grow really and your yield will really suffer.
