SHOULD I DECREASE LIGHT TO 10 HRS TO SIGNAL TO THE BUDS ITS SNIPPIN' TIME? I'm in no rush, only that the light setup is not ideal for younguns! Don't wanna bully them til they're frail and weak... and not dank.

LEDs lumens
is there a method (which does not involve the purchase of a rather expensive device) to measure the lumens present in the growbox? I would like to make sure that the LEDs that I bought have the same performance declared on the package 😕

Yellow spots on leaves
Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?

One of my beauties is showing for the first time a nutrient issue, a couple of leaves are showing yellow colouring, the very rest of the plant is homogeneous deep green so i assume she is almost fine, but i really want to listen to her and care, I think it could be nitrogen def

Mars Hydro ts1000 info
Looking to upgrade my flower tent light to a Mars Hydro TS 1000, is this a good light for a 3x3 tent? It says coverage area 2.5x2.5. My tmlapy 1500w will be going in to the new veg tent. Also, is it safe to swap lights mid flower?

Light hanging distance
I’m not sure how high to hang my light. My plants seem to be all staying extremely squat and not stretching, though all seem healthy. I’ve been fiddling between 18-28 inches and 600-800 ppfd (ios meter app) and I can’t find a distance that seems to make them happier. D26 autos
