Light height and intensity
Hello all. Recently I upgraded my lights to 2 mars tsw 2000. I've noticed my plants are growing slowly compared to everyone else's. I have it set at 24 inches 25%. However a mars hydro admin posted 12 inches 75% during veg? Isn't that like 1500 ppfd? I'm so confused.

UV LED slowing down growth? Sorry previous question without the question!
The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.

I have a photoperiod in a 5 gal using BAS light. It is currently day 3 of week 4 , and I'm getting some damage on the tops. Would this be light stress or another issue? The tips are starting to go light green. Using the 200 watt light for the 2x4x8 ac infinity tent.

When to switch to red?
Hey all growmies. I have a 420 FB Purple Punch going. She’s three weeks old tomorrow from sprout. I’ve had her under blue light so far. When do you reckon I should switch to red spectrum light? What do you guys think?

Light distance and when to top?
I'm using a 300W LED. What distance should I keep the lights at now that I've transplanted and the plants are doing well? I'm thinking 24" and then move up as they grow until flipping. Also, when should I top? I've read that waiting for 6-8 nodes is the right way to go.

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.
