Diagnosis? Help-a-noob. w/PICS Purple pistils!

First I'd like to say, this is a great forum. I've been a long time lurker; never joined for fear of big brother. But, I've got a problem and it's spreading. I've been searching for answers for the last 2 weeks and can't pinpoint it so I'm reaching out to you guys here.

Bagseed, looks mostly indica.
120 days
Soiless mix - peat, perlite, aged pine bark.
Chicken shit tea diet

Now, as far as pH goes. I wasnt monitoring it, even tho I own an expensive digital liquid meter. I did finally test it about 4 days ago but I think my results were skewed bc of the hydrated lime I had sprinkled on the surface about 3 days prior to testing.

My pH was 9.2, but again I could see the white lime in the test water. I flushed the lime, and transplanted from a 3 gal to a 5 gal pot and added more soiless mix and no chicken shit. The run-off then tested at 7.5 pH. I have 2 plants basically fed the same way the whole grow. The 2nd plant has a touch of this problem but not an alarming amount.

I now adjust my water pH to 6.5 prior to watering and I've held off on feeding in case it's a lockout.

PROBLEM:

Starting at lowest fan leaves, chlorosis spreads first from veins, then from bottom of leaf towards the tips until entire leaf is yellow.
Also note, the downward curl or "claw" look to fan leaves.

New growth is unaffected. But fan leaf problem is slowing climbing up the plant. I'm about 10 days into flower.

Oh, and this plants pistils are pink/purple. Hard to see with my camera's pics but you still can kinda. It's nice lookin for bagseed.


Any advice is appreciated thanks!

anyone? Not even a comment on the pistils. I thought for sure that would trigger some curiosity.

Looking the first couple of pics it looks like an over watered and forced fed plant with a touch to much PK and not enough N in the mix?
Are the pots heavy?
If so don't water.. If not just water with plain ph'd water for a week or so when needed thats what i would do anyway

Your plant looks healthy just a little hungry, I would imagine with pH as high as 9+ you have managed to lock out just about everything. If you pH is back to normal and stable give some food and see if that alleviates the issue. I would not worry over the pink/purple pistils.

regards,

thanks Cannabutt. They look Overwatered? You mean bc of the droopiness? They're usually not this droopy but the pics were taken in the early morning. The leaves are all horizontal now. I typically dont water until they are sagging, and the soil is dry a cpl inches down.

What's indicating to you that there's too much PK (so I know what youre looking at)?

Thanks again

Yeah, I've gone thru that several times. I cant find any info on yellowing begining at the base of the leaf and working its way to the tips.

I thoht it was N toxicity. But now Im not so sure.

Ya know they look good to me-the red stems happens with clones alot/ type of strains/ or in need of food.The yellowing of you leaves tells me it is sucking up nutients and doing what it is suppose to-"Keep on rocking!!!"

Sorry, probably not over PK The lower plants fan leaves look N deficient as well as the top fans looking droopy
post some non droopy pics

Since you are flowering you need more P then N-The plant will be sucking up more nutrients to produce the buds-FOOD!

I'm leaning towards a overall lockout of available nutrients due to the high pH. Hydrated Lime can change soil pH very quickly, particularly when heavy-handed in it's use. Even though you had applied it and it was only in the pot for about 3 days, it is more than enough time for the pH to be raised significantly. An initial pH result of 9.5 is a fairly high result and no amount of flushing would quickly lower it as the hydrated lime will bond with the soil at the molecular level. At any rate, the effects of a excessively high pH can lockout N,P,K or, all three macros. In this case I would check the runoff pH before and after fertilization, then use a acid such as "pH down" to get the desired runoff of 6.2-6.6. This may entail getting your fertilizer solution to levels as low as 6.0 or less.

A good balance of N P K is paramount growing plants using any medium, soil acts as a buffer. plants in flower run out of N too early most of the time! work that

Thanks for the replies guys. The run-off pH today was 7.02, so I'm hoping it was just a lock-out and that once the medium stabilizes everything will pick back up.

The pistils are getting more and more purple everyday. (see post below for pic) I love it. I'm pretty sure the coloring is genetic since her sister and brother have some purps in the flowers as well.

Carl, I thought flushing was more effective when using a soiless mix, such as what I'm using. It's a blend of Peat, perlite, and aged pine bark. I opted for this mix in hopes to have a little more control of feeding - specifically, if I overfed.

This is my 3rd grow and I've always used a good organic potting soil til now. I find the chicken shit tea tends to make soil pretty acidic over time.

Sorry, added the purple pic to the wrong post. Oh well, here's a shot of the purp's.

Soilless mixes are generally effective at flushing out excessive salts due to it's porosity but, in this case, the addition of both pine bark (pine fines) with a relative pH of 4.5 or lower and peat moss which is quite acidic with a pH of 3.6-4.2 likely lowered the initial overall pH to extremely low levels. What was the runoff pH prior to the addition of the H. Lime? How much H. Lime was added as an amendment and when?

I hadnt checked the pH until I noticed the problem. I used about 1/4 cup of lime sprinkled on top and watered in about once a month for the whole life of the plants just to counter the chicken shit and peat. I shouldve been checking my pH, but the plant was growing pretty good so I never bothered.

I'll just keep watering with adjusted plain water and keep an eye out for signs of def. I'm pretty much convinced this was a lockout due to pH, and the plant was sucking the mobile element out of the fan leaves. The top of the plant has always looked pretty healthy and it doesnt look overly green to me, which would indicate a N overload. There are some distortions on the small trunk leaves tho, which confuses the situation even more.

thats a gorgeous purple, even the stems are that very deep, purple, lookin nice

Thank you sir! It's getting more and more predominant every week. Definitely genetic too. I guess you could say, Bagseed is like a box of chocolates, you never know what you're gonna get.

Im pleased.

yea ppl knock bag seed all the time but i dnt mind it, beat 50 bucks for 10 seeds or w/e, this year i got my seeds from my brother, he baught a bag off some1, the guy he got it from ran a hydro system and my brother said it was real good, and sticky, loaded w/ crystals but the guy musta left a male in cuz there was a ton of seeds in the bud, fine by me i get a bunch of seeds outta the deal, hell its only a week in budding and im already starting to see trichs form, cant wait for the finished product

jeez so many odd answers, 1st tell us what your nutes NPK ratio is and what your temps are for day and night time please.

the purpling is from P getting clotted stems, this happens usually when its cold, especially in the skinny stems (anything below 65 degrees), and also happens when there is a lot of P. K regulates the water intake and plant respiration, K should always be the highest nute (thats what the gow bible and a few college studies say anyways). the lower leaves yellowing and dieing is from N deficiency(probably from bloom nutes), the downward claw is over watering(looks similar to salt build up but your plant is going defficient so its not), and over watering suffocated the roots and doesnt allow them to absorb N at all... thats why your plant is eating the N stored up in the lower leaves.
