Looks like no long term damage from being in low temps for a few days and seems to be doing great. Did some light pruning and light is back to being on 20 hours now that it doesn't need to heat the tent. Friday or Saturday I will do the first top dressing and swap the LED out for the 600w HPS to power the flowering.
@KingSalomonsWeed, It is more of an experiment and to see any difference between the LED and HPS. I have had good luck with the LED but the only time I used the HPS was my first indoor run and because of the soil I used the plants didn't really grow good and were stunted. The bud was good but didn't get much at all and now I have more grows under my belt, I want to give the HPS an honest run before I decide to upgrade one way or the other.
