I'm in week 2 of flowering my autoflowers. Four are in a tent with HPS and are doing decently well, but have yellow/brown spots on a lot of the fan leaves. I took off the ones more than 50% dead/damaged. The bud production is still doing well, but they aren't growing any taller. They just had to do without 30~ hours of light/air/etc. during a power outage and were moved during week 2 of vegetative from a humid and hot upstairs to a cooler basement (maintained at 72 in the tent, down to high 60's at night). I have used fox farms soil and fed them 1/4 strength nutes from fox farms as well. I can't tell if I am over or underfeeding them. This IS my first grow on my own so I'm still learning (did one prior with my caregiver, non-autos). The tips of the leaves are all still green, so I feel I am underfeeding them. But I keep hearing autos are very picky on nutes, change in light pattern, overwatering, etc. Next grow I am going back to normal fem seeds since I had no problems there. Anyway, same everything for my other 2 plants in my second tent. Only difference is they are under a Advanced LED Lights Diamond Series XML 350 light. They have been moved a little more since they went from the HPS to this LED tent about 3 days into flowering. They have a few more spots on the leaves, but these were also my two worst plants from my other tent. I snapped the stalk on the Skunk (1 out of 3 Auto Skunk Mass, no skin broken and it supported itself with no additional help) and the White Widow (1 out of 3 WW's) was the slowest of the group. They now have really fat, hair ridden, trichome-laden buds. Other than their fan leaves, they look like they are producing equal or better bud than the 4 plants under the HPS. To my point, should I flush? I will get pictures soon (within the day). Other information. 4 plants (2 Skunk and 2 WW) in the shared 4x8 are on one side under a 400 watts HPS with another 400 watt in the middle of the tent and one more on the other side. LED tent is a 4x4, 330 watts actual draw. Everything is on a 18/6 cycle. I water about twice a week, slightly more for Skunks and slightly less for White Widows. My judgement for watering is weight of the plants and seeing if the leaves are curling (need) or "fat" (good). I fed them 1/4 nutes twice on the first week of flowering, then 1/2 nutes on the second week (only once in fear of burning them). Tents stay between 64 at night and 72 during the day (75 for the HPS tent). Humidity during the days is around 45-55% with it reaching 65% at night. Any advice is helpful.
