purple leaves (PICS)

plant is about 10 weeks into flowering, started seeing purple about 4 weeks ago. I seen a post somewhere from the 2001 edition of jorge cervantes grow bible that said purple leaves is possibly from too much salt build up so i flushed them out and have been giving them straight ph'd tap water for the last 2.5 weeks. The plants have only gotten more purple since the flush And i don't know what is causing it. Help

What is your experience level? (first timer, novice, experienced...) (novice)

Your Equipment:
.1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's) (400w hps)
.2) Distance from tops? (12~ inches)
.3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...) (none)
.4) Is there a consistent fresh air supply? (yes)
.5) Do you have an exhaust fan and a circulation fan? (circulation)
.6) What are the bulb wattages, kelvin ratings, and schedule? (hps bulb 12/12)

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...) (FFOF+20% more perlite)
.8) Size of container. (6 inch by 5 inch high)
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? (no)

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) (tap) What's it's ph before adjusting? (~ph 8)
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...) (ph pen)
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) (ph down)
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. (last feeding was about 2.5-3 weeks ago about .75 tsp per gal of foxfarm growbig+tiger bloom) flushed around 2.5 weeks ago and have been giving them straight ph'd tap water ever since)
14) How often are you watering between feedings, and how much per watering? (was feeding every other watering 3/4 to full strength foxfarm nutes)
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) (no)
16) Are your ph levels stable, or do they fluctuate? (tapwater out of tap? can fluctuate between 7.5 - 8.5)
17) What is your ingoing water's ph? ...your runoff ph? (ingoing 6.5 - 6.7, runoff 6.5)
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? (no)

Your growroom:
19) Indoors or outdoors? (indoors)
20) What size of closet, room or hut? (small bedroom 15ft by 15ft approx)
21) What are the temps and humidity levels while lights are on? ...With lights off? (on ~75-80, off ~65)
22) Have you seen signs of insects in the growroom? (no)

Your strain:
23) What strain are you growing? (bagseed, i assume indica)
24) From seeds or clones? (seed)
25) Is this an autoflower strain? (no)

i might be wrong about this, but I know of many strands that naturally ave purple leaves.. (ie. Purple Kush)... those girls look great, i would think you are doing just fine with them.

sorry.. i meant to say more, Those are ready for harvesting, i would cut them and hang them immediatley.. 10 weeks of flowering is more than enough and you can see most the hairs have gone orange. The purple kush, and many other purple strands get more purple towards the end of the flowering (more experience people please feel free to correct me if i am wrong)

First look I'd say just from the temps getting low during the night....That frigid air....

those purpling are from the strand. only be worried if leaves turn purple while in veg state.

which in case a lot of times would then be from having to much phosphorus...Usually starts in the stalk/stems. :thumbsup:

The bad purple is mainly when your stems turn it I believe.

Those look ready from here.

I completely agree... Most strains will turn purple if the temps are low in the night cycle during flowering. It's a defense mechanism of the plant to protect from the cold. I hear anywhere below 70 degrees F will make it happen.

However, People will love the way your bud looks... it's a common misconception that purple = amazing.

Those buds are ready, i would say it is the strand and possibly cold as Italian said.. i put my exhaust fan on the same timer as my lights so that the cold air at night is not pumped into my grow tent.. you should not be going below 70 definitley not down to 65.. but better you know that for next crop cause this one is done.

lots of strains have purple leaves while flowering. I find it actually really pretty. Your plants look good but ready to pull and hang. I wouldn't let them sit any longer in your grow room. 10 weeks is a really long time to flower plants. I would stick with the basic 8 week rule. :jointsmile:

TO BE SURE ITS DONE:

Harvest time is NOT DETERMINED by how the calyxs look, but by how the trichomes look. The calyxs turning red will not accurately tell you when to harvest.

get a magnifying glass and look at the trichomes... they should be getting a little cloudy looking if they are ready for harvest. wait even longer (till they are cloudy and amber colored) for a stonier high.

Better yet, look at this guide.
Pictures on When to Harvest - Trichome colours - 420 Magazine

It explains the coloration of trichomes relative to harvest times and types of highs. pretty cool shit if you ask me.

good luck :thumbsup:

this video sums up when its ready

http://www.youtube.com/watch?v=A_r0_2ohTjk

you can get a microscope on ebay for about 5 bucks i just boguht one.. but don't wait with yours, i guarantee they are done..

I would agree that if you harvested them this second you'd have some tasty smoke, probably with a headie energetic high. If you're looking more for the stonier, more narcotic high, they aren't necessarily ready. the only way to be sure is with a magnifying glass.

thanks everyone:), almost 2 days without a response than 13 in 2 hours, interesting. i figured that most would say temps. I've been checking the trichomes with a magnifying glass but still no amber on any of my plants and all 3 of my plants are different strains. I think I gave them a little too much nitrogen in flowering which delays maturity.

Yeah, from the pictures the trichomes do like a little cloudy... so you could harvest if you want. but if you're growing for medicinal purposes, chances are you're looking for a more narcotic high. i've heard of people letting plants flower for up to 12 weeks for this purpose.

It all depends on what YOU want.

Good post, but what you meant to say is don't go by the pistil color, the calyx is the body that surround the pistils or "hairs." :thumbsup:

......:stoned:......

is a magnifying glass enough?

idk, I've seen some strains that go that natural "autumn" color in flowering. Like Soma genetics rockbud. Which a little like your avatar. But like I said before, it's more than likely just cold temps from the night time.

looks like PK to me.

It doesn't look at all like PK to me, besides if you look at the troubleshooting form you'll see it gets down to 65 at night... cold enough to turn almost any strain purple.

My plant turned reddish for a few days when the temp dropped to 70 due to a cold streak here, but returned back to green pretty quickly. The cold also seemed to bring out a more fruity smell that also faded when the temp went back to normal...These plants are truly strange :cool:

They are the strangest plant on earth if you ask me. People are willing to go through hell and high water for it. It makes nearly everyone peaceful, even if only temporarily. It changes lives. It's fucking incredible.

I don't know about your area, but around here eighths are literally half the price of gold. 3.5 grams of fine gold is worth approximately $120, eighths of dank around here are $60. i think thats crazy.

Very strange plants indeed.
