@GreenRN,
Hi! Yes, it seems you have a bit of light burn.
In my experience, i noticed this:
led light have "hot spots" too and under 24H, the leaves under those will get light burns first. To avoid light burns, either you give everything right in terms of environment and feeding or is better to keep the canopy below that level until is early flowering, to promote vigorous flowering. You will probably get some light burn, but many more flowers too :).
The more even is the light and the more even is the canopy, the easier to manage light burn.
Always go step by step with light height, so you can easily revert back with not too much damage.
My personal reasons for 24:
i can keep the plants compact (i have limited space);
it is easier to reach the highest bud to light ratio;
to keep the initial setup cost budget lower:
100W at 20hours = 2000W/hour
100W at 24hours = 2400W/hour
to make fat buds (again because of low stretching)
@GreenRN, they have a fairly good spectrum, maybe they lack a bit in the reddish part of the spectrum, to promote flowering. If you have an hps, i think it's time to put it on :)
Beside that, if you want more yield, for the next run, you may want to start lst, hst, fim, defoliation and so on.
The objective is to make the highest number of buds under the light in the end :)
In this scenario, is better to have a bit more plants in smaller containers, they will finish in time with the schedule and they will compensate a bit for the increased hours of light.
The procedures will stess the plants a little, so they will need a little bit extra care.
Have fun!
@OneDude, I don't use LEDs, I use Ceramic MH, if that makes a difference. I did raise the light up about 2" and I think that's helped. Leaves not taco'n as much. So thanks for the feedback.
@GreenRN, lol, that's funny about the exhaust fan, great minds think alike I guess. I fell on some Ice once and my shoulder has never recovered, I know shoulder pain for sure.
@BeefWellingtons, funny you mention the AC Infinity Cloud Line! I have the 6" and love it. I was hesitant about the price at first, but I am extremely impressed. I think Im going to turn it up some. Thanks for sharing the filter info, i will definitely look into that brand. I appreciate it. Thanks, shoulder surgery is no fun!
@OneDude, thanks, so far so good. Poster above mentioned it looked like might have a little heat/light burn, I'll raise my lights up more to see if that will help. Have you had any issues with 24/0 lights with your autos that I might need to watch for?
