This is my first time grow in life. I started with 2 auto big devil xl,
due to less research i start my sprouts in medium size cup
Now i know that i should have started them(autoflowering) directly in their final pot, anyways seedlings did well and i transplanted them in their final container after 2 weeks.
I choose big 10, 12 gallons big pot because i want heavy yields and big plants.
I used good manure fertilised black brown sticky soil
I mean i use soil medium (some good soil)

Light Timings

Using 20/4 light schedule

HUMIDITY
  • Week 1st: 70%
  • Week 2nd:65-70%
  • Week 3rd: 60-65%
TEMPERATURE
  • DAY TIME : 24-27° Celsius (75-81)°Fahrenheit
  • Night time : 3,4 °Celsius less
Lights
  • Cfl and white led bulb mix
  • Both 6500k cool lights

Lights i will be using are
For veg
6500k (4,5)cool light led bulb of 50 watts normal led household bulbs
about 250 watts (true)

6500k cool light cfl 5×25watt(true), 2×70 watt (true)
Total 265watts
Means total 515watts(true) cool white 6500k

And for flowering time
  • I will add about 3 bulbs of 50 (true) watt warm white led bulbs 5000 lumens each (2700k) -- 150watts total
  • And 4 20 watt (true) warm white 2000 lumens each 2700k To fill the blind spots --80watts total.
  • Total 230 true watts warm white 2700k
So a total of 515 watts and 230 watts for flowering
TOTAL 745 watts(true) light
Expecting 500grams dry yeild

I know its lots of light
Thatswhy i have used xl pots and will use good amount of NPK

I started with 2 25watt cfl bulbs on seedlings and they did well
I placed lights about 3 inch from seedlings
I used a lux meter
And put my seedlings under 8000-10000 lumens for week 1
Then i increased lumens to 12k-14k lumens in week 2 by placing lights closer.
All went well,3,4 true pairs of good green leaves pop up in 2 weeks
When i decided to transplant them, i watered 1 day before and now i softly transplanted my plants to moist(not to much) soil prefilled 10 gallon pots, then i moderately watered and 4 hrs rest time is on, lights off.
Next morning plants seems normal, but not growing,
Again after 12 hrs plants started to grow again.
15 days and everything looks perfect

Plants are now 17 days old
2,3 days after transplant one of my plants look little pale
Upper leaves are turning light green.
Dont know whats the reason.
Please Help.
also i added 40 watt 6500k cool led bulb today and increased lumens to 18k

Sounds like you got it all covered, bud, I wouldn't worry one bit about the light color, on one of your plants, mine do that most all the time.
Looks like you might should have used some perlite in your pots though,
biggest pot I ever used for an auto was 5gallon, biggest harvest I ever had from an auto was in a 3gallon pot, a NorthernLights auto from Nirvana, got just a few grams short of 8ozs, dry bud .
Grown quite a few that got 5-6ozs, dry from, autos.
476 got way over a pound from one auto.
Are you gonna use cfls, the hole grow?
 
Most likely culprit is probably calcium deficiency or lock out I’m not 100% but it happened to me and I flushed the system waited a week before I gave any nutes and she’s back to doing her thing..
but because your using soil you can’t be 100%
maybe something was in the new soil she wasn’t used to and she’s telling you
 
Lights i will be using are
For veg
6500k cool light led about 250 true watts
6500k cool light cfl 5×25watt(true), 2×70 watt (true)

I know its lots of light
Thatswhy i have used xl pots and will use good amount of NPK
 
I didn't used any nutrient still
Will start giving npk in 3rd week
The soil is from my farm
And i can guarantee that it is the best soil available in india for agriculture
Also i added little natural manure to soil and mixed throughly.
 
yeah - huge pots for autoflowers - your plants' roots will spend too much time trying to figure out how big their new home is. That will hurt your yield. Have to grow the roots first with autoflowers - happy roots make for big buds.
 
So, should i give some potassium for better root development,
I have heared potash helps is good for roots.
By the way my fertilizer order is stuck due to 21 day lockdown in india.
I was thinking of giving 10 3 6 ratio npk fter 3,4 days.
Is that okay

And please tell what is wrong with yellow leaves at top
 
They look good to me. Pots are to big for an auto, plant I believe will try to grow roots instead of plant material. Otherwise everything looks good, but If they were mine I would feed a little and when transplanting add something to aerate that soil.
 
That would be a yes to your question. Aerate some soil into a smaller pot and then transplant the plant into that pot. And once settled in feed them.

Transplant once again 😟
I transplanted (which should not be done in auto because it effect yields by 5 to 10%, my mistake) them 2,3 days before and now they have started growing again after a little shock.
Should i transplant them again.
Won't it will give them shock again 🥶🥶
 
Yeah i get notifications for whats going on my post
But do you guys get notifications of only comments or both my comments and reply in my post??
 
Yes I get notifications of your replies. It’s your choice if you want to transplant or not. I give advice on what I would do if they were mine. If that plant was mine I would transplant to a pot with aerated soil. Just giving advice based on my experience. Yes autos can be stunted by transplanting. But they can be stunted by soil that is to compacted.
 
Cannabis roots love oxygen - that's why you see most grows with about 30% of the grow medium being perlite or vermiculite - for aeration.
As loose as some of the grow medium is that you are using - gravity and watering will eventually compact your mix - making it difficult for your roots.
Not sure about the other things you asked about - don't use them.
Yellow leaves is the newest growth.

Before you are ready for them - your plants should soon begin to shoot up pistils.
 
I have had so/so luck with autos. Really depends on genetics, I have grown some that stayed small and still yielded 3 ounces of quality smoke, best I have done with an auto is 4.5 ounces out of one plant. But I only grow autos usually outside during our growing season in the USA.
