@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!
