Lighting Fugue State, Autocobs, and Advanced Nutrients

Thanks for chiming in slow... I just finished a bit of work on them (cleaning up some garbage leaves and opening things up and a bit of tucking. Also snipped off some sites that were at the very lowest points and in tight against the base of the plants) backed off the base nutes a bit as well with the new jug I mixed and gave them a light watering.
Now, something crossed my mind as well and maybe @BigSm0 can give some input on this... about 2 weeks ago I decided to position the plants much closer together kind of in a triangle since none of the growth had extended beyond the pot. My thinking there was if I pack them in tighter, I can bring the lights closer together and get the most amount of light possible out of the three autocobs. With the overlapping footprint of them from being so close together. I’m starting to think that it may have been too much light?? What do you all think? I’ve now spaced them evenly across my 2x4 with one autocob above each as opposed to a triangle formation that had each Autocob within a foot or so of each other. Also I noticed when I had them bunched closer together the sides that were now closer to the walls of the tent had weaker growth since that formation was essentially 2 wide and 1 between the two. I am fairly confident that going forward things are going to be much much better. Looking forward to progress and hopefully a decent stretch this week. Think I might just raise the lights 3 inches before I close the book on them tonight
On my current grow I initially put too many COBS too close to the canopy and the leaves never taco’d nor drew away from the lights but rather they prayed to the light and then started showing deficiencies rapidly in the cal/mag and manganese. I had 4 of the AutoCobs (220 Watts) at 24 inches away from an older plant and it was just too much. I raised the lights back up to 32 inches, turned two of them off, and upped the calmag in he reservoir. They were back to normal almost as fast as they were having issues. At no point did they show toxicity claw or overwatering drooping. Here are some pics of what was happening. https://www.autoflower.org/threads/...ht-stress-in-action.65376/page-3#post-1838267

Within 2 weeks I had all four of the lights back on, but still at 32 inches. 3 weeks later and all looks wonderful again and the lights are still at 32 inches. 7D4925AA-7753-41AB-98DF-3B863659C0C9.jpeg In the future I’m just letting the plants veg to the lights, not the other way around. In bloom you can get a lot closer with them and not have these issues. When vegging I think it just causes them to use a lot more of some micronutrients.

So I guess what I’m trying to say, but have smoked way too much tonight, is that light placement is important with COBs but I don’t think they are what caused your current issues. I know and I think @BigSm0 would agree, we still have a lot to learn about the best way to utilize cobs to their full potential.
 
View attachment 935719 View attachment 935720 Ok. Lights are 28 in above the 2 shorter ones and 27 above the taller one. Let’s see what this week has in store for us!
To many cobs just run 2 for now to be honest. Them smocobs are powerful! def an adjustment and I'm still getting used to them. Had about 6 harvest already with them. Just my personal opinion Don't wanna give to much hahahah unless them ladies stengy!

I actually read that thread earlier. Basically I had the 3 autocobs placed within a one sq. ft. Area. Picture a perfect square that is 1x1... now picture an autocob on all corners except one- this makes a triangle. That was basically what I had going on earlier. I just got up 20 mins ago to let the new rescue dog out to pee! Buddy scared the shit out of me and jumped on my bed and partially landed on me while I was in deep sleep so since I was up I decided to check in. So forgive me if I seem a bit scattered right now! Thank you all for taking the time to follow along and providing your input. It is greatly appreciated. I’ll check on the girls in 2 hours when I’m getting ready for work. Bye for now...

Well now that they’re properly spaced out, I’m ok with one over each I also need them all on for temps... if unplug one I’ll be hard pressed to get above 20C most days

Just out of curiosity, how close was that 1x1 arrangement to the canopy? 1x1 sounds like they were right next to each other with just an inch or so between the heatsinks. That has to be intense, I was going to try it but don’t want to mess with the arrangement I have as it is working. My current is in a 3x3 with the 4 lights spread evenly and at 30 inches I’m probably averaging 22000 lux everywhere on the canopy. At 24 inches same spread it was above 30k peaking upwards of 40k. I can’t imagine what it was in a 1x1, but will find out when I can. Did you see the post where @Waira was using a post it note as a protective cover for the cob and forgot to take it off? Turned it on and in no time was burning a hole straight thru it. That’s an intense light.

Hey Hemi! I guess my post was a little too open to interpretation! Lol. I should’ve said that the cobs had a foot between each other (heat sink edge to heat sink edge.) distance from canopy was 24in. Side note: the tallest plant was 5 inches taller than the other two so although it was consistent at 24in above the plant, it was 29 inches above the 2 other plants. But the 3 autocobs were still probably too much light considering the footprint I was using at the time for the 3 plants.
 
Yeah I saw that post a few weeks ago. On my last run I realized it first hand when I put a piece of cardboard up to the cob to block out the light as I wanted to see what kind of of light spillover was hitting one of my plants from the next light over. Within seconds I saw smoke! Very powerful little lights indeed! Also on my way out this morning I had a quick peek into the tent and it looked like they were starting the process of perking up. Hopefully things get going on the right track and stay there till a bountiful harvest! Lol!
