Here we go... week 2!
Everything went pretty smoothly during germination and week 1.
I'm starting to think about nutrients, as i do plan to start feeding, VERY lightly, sometime this coming week. I figure my soil should probably be okay for 3-4 weeks but i'm going to be feeding only 2 of the 3 plants starting in week 2. I'll start feeding the 3rd plant in week 3. I want to see if there's any difference or problems that arise.
Day 8:
- Temp: 74-80F
- RH: 68-71%
- no water, reduced exhaust fan speed to 10% at night due to colder outdoor temperature.
Day 9:
- Temp: 72F-79F
- RH: 62-69%
- lightly watered with de-chlorinated tap water
Day 10:
I've now desgnated the plants as "L-1", "L-2" and "L-3", based on their germination and seedling stage growth, with "L-1" being the most vigorous.
- Temp: 72-76F
- RH: 65-68%
- Lightly watered "L-2" and "L-3" with a very weak nutrient mixture using Remo Nutrients' "Micro", "Grow", "Velokelp" and "MagNifiCal".
Remo's feeding chart recommends 6ml/gal for week 2.
I used .5ml/.5gal... 1/6th the recommended dose.
- "L-1" was watered with just dechlorinated tap water.
- Both adjusted to pH6.5
Day 11:
- Temp: 69-76F
- RH: 62-68%
- No water
- added sticky traps for fungus gnats, which have afflicted one of my girlfriend's orchids in our house. We've quarantined the orchid and will be giving our houseplants a few doses of BTI.
Crossing my fingers that they don't cause me any issues in the tent!
Day 12:
- no signs of fungus gnats in tent
- Temp: 69-77F
- RH: 62-68%
- No water
Day 13:
- no signs of fungus gnats in tent
- turned humidifier off
- ambient RH is about 60%
- Temp: 69-77F
- noticing leaf edges curling. Possibly due to high RH and/or over-watering.
- Calibrated pH meter. Was off by +0.3 pH.
- Watered lightly with pH adjusted tap water @ 6.4pH
Day 14:
- No water
- Replaced the 24" Sunblaster T5HO fixture with a 24" Sunblaster LED, which now makes two of them.
I plan on switching the 6400K T5 bulb with a 2700K bulb in the T5HO fixture.
Once flowering starts, I'll pull out the two 6400K LED fixtures and put in the 2700K T5 fixtures (I still need to pick up one more T5 fixture so that i have two, which i'll be placing at either end of my 2x4 tent as supplemental lighting).
- Distance to canopy (24w Sunblaster LED): 12"
- Distance to canopy (HLG Elite 360): 24"
- Elite 360 Light Intensity: 35%
The 2nd week saw a couple of challenges arise, including over-watering, fluctuating temperatures and a fungus gnat scare.
For week 3, I'm switching to a 20/4 light schedule, raising my pots off the floor on wire racks, doing some low-stress training and lightly feeding.
Day 15:
- lightly watered with Remo Nutrients, at 20% recommended strength, pH'd to 6.4
Day 16:
- no water
- started some light LST on #1
Day 17:
- no water
- continued LST on #1
The short inter-nodal length makes it a bit of a challenge to train. I suspect the two 6400K Sunblaster LED's have contributed to stockiness.
- topped #2
I decided I'd do LST on 1 plant, top 1 plant and let one plant grow naturally to compare the differences.
Day 18:
- watered with de-chlorinated tap water, pH adjusted to 6.4/6.5
- pots felt very dry when lifted, prior to watering. I think i can combat the soil water retention issues by keeping them on wire racks.
- continued LST on "#1"
Day 19:
- no water
- no training
Day 20:
- no water
- increased QB96's light intensity from 40-45%.
- LSD#1: continued LST, leaf tucking
- LSD#2: LST, leaf tucking, trimmed off 1 lower branch that was under-developed.
- LSD#3: no training
Day 21:
- watered with 5ml/l (80% recommended strength) Remo Nutrients: Micro, Grow, Velokelp, MagNifiCal.
- leaf tucking on all 3 plants (minimal on #3)
Week 3 is behind us.
All 3 plants have recovered from the early over-watering issues but i'm still seeing minor deficiency issues that I'm hoping will improve as i increase the nutrient schedule.
I'm really hoping week 4 brings some substantial growth, as i doubt i'll get a 5th week of veg before pre-flower pistils start showing up.
You can start seeing the difference between the 3 different training techniques I'm using.
LSD#1 - Aggressive LST
LSD#2 - Topping & LST
LSD#3 - No training
Day 22:
- no water
- continued LST on plant #1
Day 23:
- no water
- signs of deficiency... Possibly Cal/Mag?
Day 24:
- signs of deficiency worsening.
- new growth appears "spindly" (thin, weak)
- watered with 50% strength of just Remo Nutrients' "Micro" & .5 tsp Plant Prod's "MJ Spike (CaMg)" per gallon.
- water pH'd to 6.5
Day 25:
- no water
- signs of deficiency worsening.
- new growth is very spindly
- leaf discoloration worsening
I could use some advice here growers. Am i looking at a Cal-Mag deficiency? Manganese? ...Zinc??
Could there be some lockout issues happening here due to over-fertilization of, say, Nitrogen??
Feel like i'm stabbing in the dark in all directions here.
Day 26:
- Flushed plants #1 & #3 with 6.4pH dechlorinated tap water.
- Run-off pH was 6.5 and was relatively clean looking.
- Assuming Nitrogen toxicity, combined with minor light burn.
- Moved 6400K Sunblaster LED strips up to match height of QB96's at 24" from canopy.
- LUX measurements at canopy range from 16K along perimeter, to 28K.
Day 27:
- Plants #1 & #3 looking slightly better
- Flushed #2 with pH 6.3 water
Day 28:
- Hoping things are improving!
- No water
- RH: 64%
- Temp: 66-75F
- I think it's safe to say, the girls are about to start week 1 of flower!
Starting week 5!
I feel like things are getting back on track. Still seeing signs of nutrient deficiencies but i'm hoping that switching to flowering nutes will give these girls what they've been asking for.
Some changes for this week:
- removed one of two 6400K SunBlaster LED's. (The 2nd one will come out in a few days as I increase the intensity of my main light).
- added two 2700K Sunblaster T5HO lights, one at either end of the tent for supplementary lighting.
As a reminder, I'm experimenting with 3 different growing/training methods with these autos:
- Plant #1: LST, defoliation
- Plant #2: topped, minor LST, defoliation
- Plant #3: natural, only some minor "leaf tucking" to help expose branching and bud sites.
Day 29:
- watered with 5.5ml/gal Remo Nutrients flowering combo.
- water pH'd to 6.3
Day 30:
- no water
- cooler outdoor temps causing tent temps between 64-73F. Adjusted mix of intake sources to limit some of the outdoor air intake.
- raised Elite 360 LED fixture to 26" above canopy, increased intensity to 55%
- raised Sunblaster 6500K LED to 26" above canopy. Will be removed by end of week.
Day 31:
- no water
- pots are dry but not quite light enough.
- the untrained, natural growing #3 plant seems to have been the thirstiest since her pot is lightest.
Day 32:
- watered with dechlorinated tap water, pH adjusted to 6.3/6.4
- continued LST on plants #1 & #2.
- did some minor defoliation of lower branches on plants #1 & #2.
- turned on small heater in room
- tent temp: 70-78F
Day 33:
- no water
- room heater set to turn on during lights off period (4 hrs) and twice during lights on period (for 4hrs ea) to help keep temperature swing within 67-77F
- turned off 6500K Sunblaster LED
- moved 2700K T5HO's up to approx 8-10" above canopy, at ends of tent.
- LST on main stem of plant #1
Day 34:
- watered with 6ml/gal (approx 75% recommended amount) Remo Nutrients: Micro, Bloom, Astroflower, Nature's Candy, VeloKelp.
- added 8ml/gal (100% recommended amount) of Remo Nutrients' MagNifiCal.
- water pH'd to 6.2/6.3
- defoliation on all 3 plants
- Temp: 68-76F
- RH: 59-65%
Day 35:
- plant #1 showing progressing mag def
- Temp: 72-81F
- RH: 58-64%
Day 36:
- watered with dechlorinated tap water w/ 1/4 tsp epsom salt per gallon. PH adjusted to 6.4.
- plants continue showing deficiencies
Day 37:
- no water
- light defoliation/lolipopping on all 3 plants
- lowered plant #1's pot to provide approx 24" to QB96 fixture
- Light Intensity (QB96's): 65%
- moved up Sunblaster 2700K T5HO's up to approx 10" above canopy at ends of tent
Day 38:
- watered with 5.25ml/gal (55% recommended amount) Remo Nutrients flowering line
- pH'd to 6.4
Day 39:
- no water
Day 40:
- no water
Day 41:
- watered with dechlorinated tap water w/ 1/2 tsp epsom salt per 4 gal water
- water pH'd to 6.4
Day 42:
- no water
As a reminder:
Plant #1: received LST on regular basis during veg, moderate defoliation.
Plant #2: topped, occasional LST, light defoliation
Plant #3: occasional light defoliation only
Plants #1 and #3 continue to show moderate nutrient deficiencies. I suspect possible lockout but my runoff tests at pH 6.4-6.5.
Plant #2 is the healthiest looking of the 3 but is very dark green... excess N?
Day 43:
- watered with Remo Nutrients flowering combo @ approx. 60% recommended strength.
Day 44:
- no water
- increased QB96 light intensity from 65-70%
- moved lights up 1-2" to maintain distance to canopy
- plants #1 & #3 continue to show deficiencies
Day 45:
- no water
- I might flush these plants later in the day today but I'd like the pots to be a little more dry before i do. I've put a small, 9-inch fan at the bottom of the tent to circulate more air around the pots.
Day 46:
- Picked up some new pH calibration solution & calibrated my pH meter... which was off by 0.4pH!
- watered/flushed the plants with approx. 2 gallons of 6.2 pH-adjusted de-chlorinated water each.
- runoff testing at 6.8/6.9pH, which is exactly 0.4 higher than i was testing it at, due to the calibration error.
- plant #2 is not nearly as badly afflicted as #1 & #3.
Day 47:
- no water
- temp spiked above 82F for 4 hrs
Day 48:
- no water
- temp spiked above 82-84F for 4-6 hrs
- A/C hose hooked up to tent, replacing the "room intake" duct to provide more reliable cooling. Outside air intake enters at bottom of tent, A/C duct enters at top and is pointed at QB96 light fixture.
Day 49:
- lightly watered (.5 gallons ea.) with a very light nutrient mixture (20% recommended amount) using only Remo Nutrients: Bloom, Astroflower, Nature's Candy and MagNifiCal, pH adjusted to 6.2.
- trying to avoid adding too much Nitrogen
For week 8, I've gotten my pH back on track and I've picked up an EC/TDS meter to better track my nutrients.
I'm hoping that the lockout/deficiency issues are improving.
Day 50:
- no water
- increased Elite 360 light fixture intensity from 75-80%.
Day 51:
- no water
Day 52:
- watered with Remo Nutrients flowering combo @ 700ppm
- pH adjusted to 6.3
Day 53:
- no water
- symptoms appear to be worsening, bottom leaves curling and dropping off
Day 54:
- watered with dechlorinated tap water, pH adjusted to 6.2
- runoff testing at 600ppm, pH6.5
- raised Elite 360 fixture and increased intensity from 80% to 90%
- temps: 68F-78F
- leaf symptoms appear to be worsening, lower leaves falling from plants #1 & #3.
#2's symptoms aren't nearly as bad and is showing much better bud growth.
Day 55:
- no water
Day 56:
- no water
Been struggling with leaf issues for weeks. Initially thought lockout due to N toxicity. Plants improved after flush in Week 7 but then promptly started worsening a few days ago. Is this a continuation of a lockout issue? Would you feed? Flush? Advice is welcome! 🙏
Hello VanBrando, i think there are alot of thing you could have done different but thats the past.
Lets talk about the future.
How i see it you cant do alot to bounce them back up at this stage, so my only advice is to flush them a few days until all the leaves almost are dead or yellow and brown.
After that you just cut them, dry them and cure them and hope for the best of it.
I do also wanne give you some extra tips on your next grow.
Maybe you can train your plants next time a little bit more and train them till the end of harvest.
I would open them up much more so theres more light penetrating more buds and also better airflow throug your canapy.
I'd also recommend that you defoliate and remove the lower growth that cant or almost has light to improve the buds that are under the light.
Hope it was an helpfull answer, i wish u much luck brother.
Keep on growing, Peace 😎
We've struggled with this grow since day 1 and now those struggles are showing their effects.
Plants #1 and #3 have taken the worst of it, which i find interesting. Plant #2 was the one that i topped and it's handled the stresses much better.
Day 57:
- flushed plants with pH6.2 dechlorinated tap water, approximately 3 gallons of water through each plant (5 gallon pots)
- Runoff from plants #1 & #3 reading TDS levels of 1400ppm! (tested first 500ml of runoff)
- Runoff from plant #2 testing at 650ppm (tested first 500ml of runoff)
- Plants #1 & #3 looking very rough, lots of yellowing/browning and dying leaves.
Day 58:
- no water
- removed dying leaves from lower branches
- it's possible that the flush *might* have helped... still early to tell.
Day 59:
- no water, soil still damp to touch
- increased lower fan speed from 1 to 2
- removed 4" intake duct connected to A/C unit. The outside air intake has been sufficient to keep the tent cool, even a bit too cool during the night.
- increased light intensity from 90 to 95% during the night to help off-set colder outside air temps.
Day 60:
- watered with dechlorinated tap water, pH adjusted to 6.3/6.4.
Day 61:
- light intensity at constant 95%, 18/6 cycle.
- removed dead leaves from lower half of plants.
- plant #1: buds look the weakest of the 3 plants.
- plant #2: showing more trichome production. Plant seems a bit further along than the other 2. Bud density seems to be improving, but very slowly.
- plant #3: buds still seem relatively healthy
Day 62:
- no water
- noticeable increase in smell
Day 63:
- watered with tap water, pH adjusted to 6.4
- measured first 100ml of runoff. Plants #1 and #3 showed TDS levels of approx. 400ppm. Plant #2 was approx. 250ppm
With lowered expectations, i'm still hoping these girls put on a bit more bud weight.
They've had a rough go the last few weeks but they're still showing progress so hopefully this week is a good one!
Day 64:
- watered with pH 6.4 tap water
Day 65:
- no water
- Plant #2 buds getting very dense. New bud growth noticeable.
- Plants #1 & #3 appear much further behind
Day 66:
- watered with pH 6.4 tap water
- Plant #2 is getting a very strong smell
- removed small, dead leaves, mostly from plant #1 and #3
- Temp: 64F - 75F
- swapped spots of plants #2 and #3
Day 67:
- no water
Day 68:
- watered with pH 6.3 tap water
- trichomes are noticeably increasing on plants #1 & #3, finally
- trichomes increasing on plant #2 as well
- removed more small, dead, dry leaves from all 3 plants
Day 69:
- no water
- forgot to set the A/C timer, had a temporary heat spike, 89F for approximately 2-3 hrs.
Day 70:
- lightly watered with pH 6.2 tap water
Well, i think i'm going to wrap this grow up. These plants suffered pretty badly the past few weeks.
Plant #2 has produced a good amount of trichomes but plants #1 and #3 aren't nearly as frosty and the buds aren't nearly as developed.
Day 71:
- watered lightly with pH 6.3 tap water
Day 72:
- no water
- This will be the last day of lighting for these girls. After today, i will be giving them 48hours of darkness before chopping and hanging branches to dry.
I will likely wet trim because of the state of the damaged and dried leaves. All 3 plants will be used to (hopefully) make some dry ice kief.
Day 73:
- no water
- no light
Day 74:
- no water
- no light
Day 75:
- chopped plants
- removed fan leaves
- Plants #1 and #3 still have a lot of green leaves and could have used another week or two of growth.
- hung branches in tent
- Temp: 68F
- RH: 63%
- exhaust fan set to 20%, maintaining negative pressure and drawing in outside air
Despite the issues we had growing these plants, they still really impressed us and showed a ton of potential! The dried buds were a bit wispy but were still covered in trichs and should work well for our dry ice extraction processing.
They smell fantastic and I would definitely love the chance to grow these again to fix our mistakes and capitalize on the strong, large growth of this strain.
Despite the mistakes during this grow, these "Barney's Farm LSD Autoflower" plants showed a lot of potential and a lot of promise. If we had been better able to maximize their potential, i have no doubt these plants would have been monsters!
I think the plants could have benefited from another week of growth, but we ran out of time and have to temporarily dismantle the grow area for home renovations.
We dried 2 of the 3 plants for 5 days at approximately 65F-70F and 60% RH. The 3rd plant took an extra day.
The buds are pretty wispy, but should work well for making dry ice hash.
Plant 1: 85 grams
Plant 2: 120 grams
Plant 3: 95 grams
Overall, we had a lot of fun with this grow, learned a lot and hope that our next grow will be better.
Thanks to all the GrowDiairies.com members who've left comments and helped us get through our issues. Without you, things would probably have gone much worse... we really appreciate it!
@Mrs_Larimar, Thanks, i'll try that. My last 2 feedings were at 600ppm. I tested my runoff during my last plain-water watering and it was 600ppm, which i thought was odd... Same out as what's going in? The last time i flushed they seemed to improve.
I appreciate your input, Cheers!
@JinksyGrows, Thanks, brother! Respect goes out to all the members here, helping each other and providing camaraderie, in the face of challenges and failures.
Can't wait to get my next journal started. Hope to see ya there!
Added some pics to the week, I see! 😁 Haha. Growdiaries allows nipples (check out the "Naked Buds" contest they ran, it's awesome), so if you want, it could save you some time photoshopping. 😆 Anyways, still glad to see the experiment is going well, good luck!
@MovingOn, Damn, I've been worried they might get flagged but ya, i checked out that contest and looks like it's fine.
Good news 'cause i felt like the Photoshoped pasties were taking away from the photos. Maybe i'll swap 'em out for the unedited versions. ;)
After the 48hrs of darkness, the plants looked a bit more frosty but plants #1 and #3 definitely could've used another week. Plant #1 is very spindly, with the smallest buds of the 3 plants.
@VanCplGrows,
Thank you! My first grow was eaten by my dog. So this will be my second shot at my first grow. I’m sure I’ll be making many more errors than you.
@Bigpoppachubbs, thanks! We made a bunch of errors with that grow but the strain was great and had a ton of potential. I'm sure you'll love it, best of luck!
@VanCplGrows, yeah you can see that! That is the main thing having fun and watching them change is mesmerising for sure! Also got some LSD auto on the go myself, encountered a few issues aswell.. feel free to check out my diary, week 8 coming soon with updates of a whole new issue haha
Too much water, maybe? I only do about a third or less of that per 24 hrs, or even half of that (a sixth of your volume). With around 7tsp of nutrients per gallon, that is a lot of nutrients - could too much nutrients per every 24hrs cause a lockout? (I'm not an expert yet)
@VanCplGrows, you can try to post a "Grow Question". Maybe somebody will chime in with the answer. I know that when I had brown spots like that, I added CaMg+ (a calcium magnesium supplement), and my spots stopped multiplying. I read that calmag deficiencies are common in LED gardens. *Edit: oh wait, I see that you are already using a calmag supplement. Hmm, I guess I just don't know. 😅
@MovingOn, I normally water every 48-72hrs but it really just depends on the plants. I wait until the pots are very light before i water but i definitely won't be using that "Black Gold Container Mix" any more. It has a tendency to hold water too well and the pot dries out too unevenly, with the outside few inches around the pot becoming bone dry while the core is still moist. Definitely won't be using that soil in future grows.
I really feel like most of my issues are due to a lockout but ya, i'm still too inexperienced to know exactly what the problems are... a lot of trial and error going on right now! LOL
@MovingOn,
So far, despite a few issues that appear to be affecting all 3 plants equally, the natural growing plant with no training does seem to be larger and more robust than the othets.
I'm curious myself, to see how they turn out (assuming i get my nutirents back on track!).
I am a Virgin -
Grower that is. 😁
I feel that your plants may have been light damaged from what I researched.
https://www.growweedeasy.com/wp-content/uploads/2017/10/cannabis-led-light-burn-brown-spots-leaves.jpg
I would love to know though.
You have very informative diaries
please keep it up.
I enjoy looking at the ladies too. 😎
@UglyTrucker, cool man, thanks. I always thought instagram was for "influencers", rich kids and wannabes but i'm always interested in the growing community. Maybe i'll have to put my presumptions aside and check it out.
@VanCplGrows, do you know how to ask "Grow Questions"? Someone who knows what is happening could probably reply to it, since when you post Grow Questions, they post up on the site separate from the regular feed.
What did your end smoke wind up being like? I'm growing LSD fem right now (1st grow) and I'm planning on growing LSD auto next time, but I haven't found much about how strong it is compared to the standard LSD fem. Thanks
@flatblack, Well, we turned our whole harvest into kief hash so I can't comment much on the quality of the buds but it did make some very nice hash! I wouldn't say it's super strong... But it's got a good punch to it.
