Week 3-4 Flowering - Leaves turning purple?

[goodjoint]

Hello, This is my first grow and overall the plant seems to otherwise be growing healthy and on pace with the other strains in the tent.

Strain: Girl Scout Cookies
Nutes: 3/4 strength General Organics w/ AACT's every few weeks + Added Molasses. I feed with every watering.
Medium: Organic Bagged Soil (Supranatural Brand - Local Company) - 5 gallon fabric pots
Lighting: 2 x Vipar 96x3w LED and 2 x Area 51 XGS 190 LED - 16-20 inches from canopy
Exhaust: Vortex S-Line 6" w/ Passive Intake + HVAC
Temps: 62-65 at night, 70-78 day above canopy. ~66 degrees under canopy during 'lights on'
PH: Don't check. Won't check. It's organic!



I noticed purpling of the leaves near the bud sites developing slowly over the past few days. I was thinking that it might be from low temps or could this be genetic? I started 12/12 on January 16th and saw the first pistils about 5-7 days later. So I'm not sure what week of flowering I'm technically on?

I have two other girl scout cookie plants growing next to this one and they aren't showing any purpling although they've had the same nutes and environment. However, they've all shown some signs of what I believe is a phosphorus deficiency since I've seen a couple dead leaves curling upward and falling off dried, blackened/browned, and curled into a dead, curled up, 'skinny' leaf. Am I right about that? See below...



Right now I'm brewing up a high phosphorus guano AACT in a 5 gallon bucket for feeding tomorrow @ 1:3 tea/rain water.

- 1 cup earthworm castings
- 2/3 cup indonesian bat guano
- 1/4 cup peruvian seabird guano
- 1/4 cup alfalfa meal
- 1/8 cup jamaican bat guano
- 1/8 cup kelp meal
- 5 TBSP unsulfured blackstrap molasses

I'm hoping the ladies will enjoy this treat. But I'm still not sure why this one lady is turning purple when all the other plants in the jungle aren't turning purple.
Thanks for your help!!!

First I wanna give props to you on going all organic. Beautiful plants brother!! The purple coloration is anthocayan a secondary pigment to chloro. You have a purple phenotype plant and is a keeper if you like purple. seed her since it too late to clone , or you can always re-veg. Plants are healthy and happy!!!!! I would say you re in the 3-4 week area of bloom.
The leaves in picture are P deficient and again, props on the bloom tea, that's exactly what she needs right now. It loos as though you follow your gut on this one and I think you ill be just fine if you stay as diligent.

Im doing a 5 strain auto now and also using GO nutrients, but with worm AACT containing plant/fruit/lactic/mineral/sucrose and guano ferments. Running cannazyme with every feed/water and aquashield, myco, trichoderma every other. AACT's are given 1x/week

1 last thing about the P deficiency
your night temps are low, so that will slow down P availability somewhat. Also I personally wouldn't go any lower or you will have to turn to MKP and there goes the organic.

Thank for your help, tikitoker!
Are my night temps too low? I was under the impression that anything above 60-62 is safe for night time temps and that temps in the 50s are something to worry about.
Are these purple leaves considered damaged and no longer in use by the plant? I hope this won't affect the yield too much

 

[tikitoker]

your temps at night are ok. Its just that when in flower you don't want more than a 10 degree drop from day to night. It promotes more stretch, however if you got the head room why not. The purple leaves are more desirable trait to most growers and smokers alike. Its simply a secondary pigment. Cannabis has many colors it can change but it mostly does so when in great health and mid to late flower, unless a true purple pheno, then it can show during veg but always will during bloom.

50's a soil grown plant can handle depending on age and root mass if the cold is temporary. In hydroponics however 50 is a killer for plant and roots and shocks the shit out em.

Ah I see. Great info!
Do you think feeding the AACT dilluted as 1/3 tea and 2/3 plain water is too light? Or should I bump it up to 1/2 tea and 1/2 plain water?

 

[tikitoker]

if its a nutrient tea, then feed it straight and don't worry about pH. If its just a microbial tea to maintain populations and diversity without a "feeding" effect, then I dilute as far as 1:5. There is no real way to improperly administer properly made and fresh AACT. If you think about it when you brew tea it multiplies microbe and when it's ready around the 72hr, were talking about trillions of microbes! 1 million in a pin drop let alone with a ratio of 1:5. No matter how you look at it your plants and soil benefit.

I like to saturate multiple x's per week my soil and foliar heavily AACT made with Lacto Bacillus, bacillus thuringiensis and Trichoderma spp., including T. harzianum, T. viride, T. koningii, T. hamatum along with pure powder form humic/fulvc acids and yucca.

Makes sense!
I've been brewing the teas for about 24 hours long - is that too short of a brew time? The water is between 65-71 degrees when bubbling.

 

[robert 14617]

the color you have has been marketed as a lavender strain, nothing to worry about

 

[tikitoker]

you got foam- then you got microbes. At 24 hrs its bacterial dominant and will benefit but brew longer to awaken other microbes. Some microbes like the protozoa is a preditor to bacteria. When the bacteria eat organic elements they keep some for themselves and excreat the rest for the plant in a bio available form. But when you have high protozoa #'s they eat the bacteria and excrete their donation in bio form and the nutrition that the bacteria kept for itself is now available to the plant. That's 1 reason that organic soils don't use/need that much nutrients, the microbes feed the plant, you feed the soil.

The temp is good for diversity and fast colonization times. However the warmer the water the more air you need. I run 20L/min @3psi using a ceramic air diffuser made by "Deep water Innovations"

good info from tikitoker on this thread guys. I'm organic myself but use proprietary bio biiz stuff and soil. I'd be interested in taking it a step further with teas etc like you guys seem to be doing. Although not aaaan expert by any means I suspect a spot of mag def creeping in as often happens with organics--teaspoon of Epsom salts per 2 litres every three weeks of the grow is all that's needed to solve this. anyway guys, good stuff

 

[yeah B U B B A]

good info and nice ideas but 1 question.

• - 1 cup earthworm castings
  - 2/3 cup indonesian bat guano
  - 1/4 cup peruvian seabird guano
  - 1/4 cup alfalfa meal
  - 1/8 cup jamaican bat guano
  - 1/8 cup kelp meal
  - 5 TBSP unsulfured blackstrap molasses​

what kind of ingredients is this.?

 

[tikitoker]

Its a bloom AACT

 

[yeah B U B B A]

i hate to ask this but i gotta know what this initials are because i have been seeing this a lot "AACT.?"
