TGA Subcool Pennywise from clone (selfmedicators 3rd grow)

that does happen. thats why i asked about a pattern. it happened my last grow, i recharged my filter before the grow and didn`t feel like hanging it so i sit it on the floor. the grow went well till it got down to the last weeks of the grow when 2 plants started burning, i thought it just had to be nutes so i was doing all i could do and they kept burning, then one day i seen the glare, it was only a strip that was an 1" wide and about 12" long and it basically killed those 2 plants. i had never seen anything like so i did all i could do an counted the result as another weird experience point under my belt.
i`am not sure thats whats going on here but if it were nutes it wouldn`t likely be burning just the tops, hell it could be a combination of the 2.

There really isn't a pattern. The half closest to the opening looks ok. Might look into white flex duct. Hate to use plastic because of the heat but it should be ok.

sorry to be so late with the reply but we`ve been having storms around here, storms for me means no internet.
i don`t know if i would go that far. you raised the screen which changed where the light was the last run last run. i don`t know if you had to shift the duct work or not. the best i think would be to go back and look at what you did or what did move to make that change. i`ve been marking on your pics again, those ducts in the pic look to be off the wall and kinda hanging out and over the edge some. you can also see the red eliminator of the cam on them, or that could be the light striker glow from the hps i`am not positive of which but it is a good example of the light hits them. it looks to me as they could be pushed back to the wall some more.
if you look at what changes were made you`ll find the cause, it hasn`t happened in the passed so it has to be something that`s is new, if it is coming from the ducts then move them to where it stops it or take some duct tape and put some random strips on it to break up the hot spot. i don`t see a reason to buy new ducts.

Ya it's the reflection. I lowered my light back down. I'll figure something out before next grow.

i forgot to post this sorry! but i`m glad you found it. the pic goes with my last post.

I think once the light was higher than the duct it started reflecting.

true! look at it like this everything is working in unison and 1 small change then you have to get the harmony back.
did you understand what i was trying to show on the nute burns on the tips? its not a bad thing, alot people will keep adding nutes till they hit that point and then back off just a little. i just wanted to make sure that you knew that and understood it.

Yeah I understood. She's on week 7. Hopefully the burns don't affect it much.

looking good vet. u will soon be crakin that corn.

do as little trimming as you can, but make sure you get as much of the brown cut out as you can. the brown is dead and it want come back. up the light some that should help till you can pull those ducts back.
hopefully you want lose alot. just look at it aint nothing but a step for a stepper. <-----old saying lol ...................you didn`t kill it so its all good.

this was some of what i salvaged from one of those burnt plants i had. just to give some hope, just yanking your chain you should come much better then i did i caught mine to way late.

A couple days into week 7. I plan on trimming the brown today. Just wanted to check trics before the light came on. Some amber. But not much.

I just read something on a different thread..........they said not to spray/mist water on the plants as it intensifies the light and can burn leaves! I spray twice a day. I wonder if this didnt cause it? Ive tried covering parts of the duct to see if I can see a change in light patterns and nothing. So im not 100% sold its a reflection.

they are going to reflect, the material they are made of makes it that way. it whats called hot spotting, where the light is catching an angle off bent or turned in a way that it causes a more intense light pattern. think of it like burning ants with a magnifying glass. now the easy way to detect it is with a light meter, but if you do have it it burns the plants. to solve it is kinda simple just move the item that is causing it and the burning should stop. like how the magnifying glass wont burn the ants if you don`t have in correct position to magnify the sunlight.
you can burn by foliar feeding and it works similar. but it would show more of a spotty type pattern, just like the leaves look after you spray. see the pattern i`ve marked.

I understand what your saying but I'm limited where I can move it. I lowered the light some but can't lower it much or I'll burn em that way and the ducting is pretty much where it is going to be because of the fan and filter placement. Once this is chopped I'll reaccess to see what can be done.

it shouldn`t take much an inch here and there would change the angle altogether. it`s like the prefect storm the light has to line up just right and catch the angle of the duct just right for it to work. so moving either may just solve the problem, you may have done it when you pulled the light up it may not line exactly where it was. this was a problem at one time when guys were lining cabinets with mirrors and polished metals, after the problem was identified people moved to the white paint, mylar, panda wrap,pebbled and white light fixtures. i was amazed at the duct tube as ruff as it is could concentrate the light the way its doing. this is not a common thing or not as i`ve seen.

I wonder if I could lower my screen some to gain some room for the final stretch? Either that or I may try flipping before the screen is full so I can weave the stems as they stretch. I really like the way the super cropped buds look. They all stand up like pine cones in a line.

you could do that.......is the fan still on the floor? do you have any of the excess duct left from when you first set it up? i think i see an ez fix.

Yeah it's on the floor. This is under the stairs so the grow area is 3x3 and then it slopes down. That's where the fan and filter sit

well its not going to be pretty but it should work. just wrap some cardboard around the front part of the duct and tape it up there. but what i was thinking was you could just add to the duct so you could push it back to the wall more out of the way. you could just raise the fan up some and that could give the duct some scrunch. i`m just looking at the problem area so you don`t have to change any of the rest of it.
