Changing light cycle on seedlings?
Can I run autoflower seedlings under 24/0 light cycle until they reach mature veg stage, and then move them into an 18/6 light cycle? I’m starting seedlings in a space tote, then transferring to a large tent to mature. Will the light cycle change have negative consequences?

Small light/ big tent
I just upgraded tents. It’s a 4x4x7 foot tent. I have a Mars Hydro TS1000. I know that’s not enough for that tent. But I have a plant in its 2nd week of flower that out grew the last tent. Is it ok to just keep that light above that one plant in that size tent? Thanks!!

Height Spider Farmer SE3000 week 5 flower
PAR increased to 600 PPFD, done by lowering the light to 35 cm above canopy. What do you think? is that too low? I'm using a Spider Farmer SE3000 (300 Watt). Anybody experience with this light? How high did you hang it from week 5 of flower to the end?

dli 40x40 growbox lamp distance problem
hi guys, I have a ts1000 at a distance of 50cm they tell me to lower it to 40cm but the dli would greatly exceed (60 dli photone) the recommended threshold of 40/45. Having a 40x40 growbox, in your opinion, at what distance should I keep the lamp?

6” three week old
I was wondering if I stunted my plants’ growth by having my lights at max intensity right off the bat. I also didn’t have vpd dialed in til 2nd week. Organic soil.My pulse one has said 96 light intensity since I got it..should I be lowering the intensity of bulbs til flower?

Currently running my KingLED 2000 with both Bloom and Veg switches on. Is this the correct time to go just with the Bloom lighting? There's no harm in running both throughout; correct? Except to the power bill of course. Any thoughts?

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,
Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?
