This Plant is DEAD!

3Berries which would make the problem worse. SoOrbudgal in the great words of Beavis and Butthead huh huh "Math" I have a meter and use it to set the dimmer at net height, the ol' back of the hand trick for Hid lights doesn't work for led's other then that it's like runoff for me, I don't check unless something is fishy even then it only a piece of a bigger picture.
 
Mr.furley you are a genius! I worked with lighting in the music industry but had no idea. I'm just a meat and potatoes rigger. I'm glad you're on our side!

Ok I installed the PAR meter and did some readings using Mr.furley 's numbers and found out I didn't need the extra light panels I spent last night and today installing. (bother) Took those out. Now my new grow as well as my old photo are getting the correct amounts of usable light. 350 for the seedlings and 750 for the flowering photo. Ain't science wonderful? Pics. New grow 2X Lemon Haze 1X Gelado! 1x Magnum of course. And here's the African Queen sleeping in her own privacy booth.

I'm using a hodge-podge of soil (I know it's not wise) two of my pots have a high concentration of Miracle-Gro and some Walmart dirt. The other two are more sticks and little chunks of wood. IDK maybe cedar and some dirt from IDK? But it will be interesting to see how they grow. Using 3-gal. pots I don't expect much more than 12 to 15 inches tall, but I have been surprised I had one 30 inches in a 10-inch pot! And say what you will... that was with Miracle-Gro and yes, it was potent, but I've been having trouble lately with the buds not being sticky. They still have the desired effect, but I wonder if they are living up to their potential? Maybe that's what they mean by the trouble with Miracle-Gro, IDK. I can do this grow and find out.

You'll recall in my earlier post that I had some buds that were not sticky and did not smell. Miracle-Gro was the grow medium and the suspect cause.
But.
Eureka! I have it! I think I figured out the Miracle-Gro thing. Yes, without a doubt it affects flowering. In particular... aging. Miracle-Gro touts longer stronger flowers. By retarding the aging process, you would get a younger, longer, stronger bud, but it would not age out! Therefore, never fully mature and that is what is happening to the buds on these plants. They are only allowed to become young adults... not the mature buds we want. The trichomes never mature because the plant never matures. It just gets old and dies!
 
Looking good.

Raise your light levels slowly....you should be at about 30 to 35% of Max light at your seedling stage and aim to be at about 100% a couple of weeks after flipping.

You can safely go higher than 750ųmol/m²/s, although that is a good safe target for you.
 
These girls are getting a good safe 350 PPFD. They are on an 18/6-hour schedule and could go to 24 hours, but I won't. No need to flip these girls are autos.
 
OverMedicated I've never grown autos ever and know zero about them. My veg stage goes for at least 6 weeks once I've topped them twice and got them trained into position....I think I'll switch off the supplemental red booster about 2 weeks before harvest and switch back on the deep violets..I need to read up more on that...I don't think it will impact yields but should increase turpines & perhaps THC...that's my current understanding but I guess different strains and different plants will result in lots of lovely randomness

Bluey I will increase the light on these puppies to 750 when I start to see buds forming. Then I'll most likely turn the light up to 20/4. Here they are after only 7 days. Check out the Auto Lemon Haze in the bottom left-hand corner. That girl is stocky, almost pot-sized (3-gal.). I believe these bigger stronger plants are due to you Bluey for getting me to turn on my fan! Seems that little breeze is more important than I gave it credit for. They are just barely blowing but it seems to have done the job. Soil is just right @21-Celsius. A nice blanket. Well, because the soil is already fortified with nutrients so there is not much to do other than water them for now. I tried feeding plants potted in Miracle-Gro and ended up with a terrible nitrogen burn. I could do one more thing, pH balance my water. That would probably speed up growth. But Miracle-Gro is already pH balanced in the upper 5's to the low 6's, so I don't worry too much about that either. I'm sure the low Ph of the soil pulls the water's pH down significantly.

To start I know nothing about 'autos' so keep that in mind.
Your light schedule requires a slow or staggered increase..lets say at flip your at about 50% to 65% (375 to 500) of your available 750 ųmols, slowly increase it over the next 4 weeks so max light comes in at mid flower...I go a bit further than that but also bring max in a couple of weeks later.
I don't know what you mean by 20/4...I would have thought all flowering cannabis requires a 12/12 photo period for healthy flowers and max yield, if that's what you mean. But I don't know for autos.
Your pH is the most important metric and you need to feed it the correct pH to suit your grow medium....speak to other growers who use the identical grow medium to yourself or the manufacturer of it....they will publish a pH range and you will learn what those levels mean for different nutrient lock outs....so it pays to vary your pH a little and know which way to go depending on symptoms.

For soil a pH of 6.5 to 7 is normally pretty good...but it can fall well outside that range depending on the soil.
Coco feed @ pH 6 should keep all growers out of trouble...but not always...lol

I use an Apera PH60 to test my nute mix..its super accurate and requires rare calibration..I always use the cheapest nutes available from any reputable manufacturer and the only supplement I use is silica during veg...but I honestly think I'm wasting my coin..I doubt it does 3/5th's of farkall.
 
Bluey
20/4 means just that. Autos don't need a light change do to the ruderalis Gene in the plant and will AUTOflower at roughly 30 days from seed regardless of light schedule so most growers run them at 18/6 to 24/0. This is why DLI can be your friend. Some random chart for 24/0

What is the advantage of growing autos? Smaller light, less heat, smaller setup? You would have to use the same amount of power over a 24hr period as I see light levels are about half of what I run but the DLI is still similar.
 
All of what you mentioned and yes power consumption is pretty balanced, some will disagree. Other factors is you can grow them in a veg room like me, light doesn't initiate flowering so you have a flexible schedule to work with your plants as photos it's 12 hrs off limits unless up in green lights, Biggest reason..... Autos typically go seed to harvest in under 100 days some drop as earily as 70 day.

Yield can be smaller from a fast plant but then again Iv hit lbs (plural) in a sq meter under 315w led, so do many others on here.

Thanks.

I only have 1 room. The work i have put into it was a lot...I considered a multiroom approach but given the way I have sorted this room with control and automation I figured that was enough. To only have to nail 1 successful crop a year and I have enough for all my great friends...everybody.

I'm striving for the perfect crop and loving my failures..it's humbling
 
OverMedicated
You need a pH thingy for water, get some stripes or a pen please. Nothing we do to help will work if you don't know your water pH. It's all we ever talk about round here.

You going to be able to get something to feed them for flower? I'd stay with synthetic, MG makes a bloom booster, can't believe I just said that.😖 I'd imagine you'd need some P&K soon.

I just got done with an auto and was quite pleased. Almost ready to jar. 15 weeks, I ran it a week past what I should have. Ran it on a 20/4 hr schedule once going.
