Temperature VS More Light which is better for buds size and potency
Should I continue to use two LEDS if temps are reaching 87f during flower (day 1) or just move plants more towards center of tent and use one LED for better temperatures (75f) (only growing two plants). lights are 1000w bestiva and are in a tent that is 24"x48"60".

Alright so this morning from 8am to 4pm my power was out. I transplanted last night and soaked the medium pretty well. Will this power outage hurt my girls. Did the temps being 10 degrees lower all day hurt them. How soon will I know if I get root rot or anything of that nature?

Throw out one plant?
Is it productive to kill one plant if the rest of the plants are filling out the room just fine and to promote ventilation and light penetration? I have one plant that is way shorter and behind the others due to genetic problems.

Light burn or nutrient burn?
Hey guys. The tips of my leaves are starting to turn yellow and I’m wondering if this is a nutrient burn or light burn? I lowered my ppm feeding to about 250 a few days ago and am growing in ocean forest fox farm soil. And the light is an optic 2 running just the cobs at 24”.

Switching light schedule for an auto and Phototype!
I'am growing together an auto and a phototype with 20/4 light circle. For my phototype is about time to change light schedule for flowering, will my auto be badly impacted by switching to a 12/12 light? Or should I move every day (same place but no light) the photo for the night?

Did I start LST too early?
At day 22, did I start LST too early? I feel that I may have stunted the growth a little from overheating, but didn't want to wait too long to start training. Also, would a higher-powered light cause less distance between the nodes, and therefore make LST harder/less effective?

Longer Light Cycle - Mid Bloom
Is changing the light cycle of an autoflower from 18/6 to 20/4 in mid flower too stressful? Doing so would bump my DLI enough to keep my existing light through harvest. She sleeps like clockwork but less so now in mid flower. Will she adjust in a couple days to a longer day?
