Light burn
2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

Have 2 1200 watt 2 switch LED lights at 19 inches. Currently using just Vegetation switch (assuming each switch is 600 watts) Seeking advice on light distance and if I should use both switches, Vegetative and Flowering. What is best without doing harm?

Weak full spectrum led place in front of window enough to finish bloom?
The weather looks really bad so i guess i need to take her inside a lot. I place her inside a barn in front of the glass door but she still hasnt there much light there. I ordered a 40 Watt full spectrum LED to add on the sunlight. Just read "used power 10 W" Will that be enough

Switching from led to hps for flower?
Howdy, does anyone switch from a blurple led board for veg, to a hps or similar style light for flower? Why, why not? Is it worth the little extra hassle to buy and install? I like my led just fine, but wondering if there’s more to be gained in flavor, quality & yield. Thanks!

26 hour day cycle?
ever done a weird light cycle for photo plants? like 14 hours of light then 12 hours of darkness then keep repeating I know that this is longer than a normal 24hour day. 1. 12 hours of darkness is what makes weed start flower. Do weeds know days r 24hr? Can a 26hr day cycle work

First questions about light
Since I'm using a chinese 50W led grow lamp , what is the right distance from the plant? I'm doing 18-6, but since she looks little for her age, would be useful to turn 24-0? many thanks for your help

Led Grow lights
I have a viperspectra xs4000 light 480 watts I am running it at around 25% on the dimmer switch and my lights are about 24" from my canopy. I've noticed some of my pistols wilting and looking stressed. Should I try to move my lights higher or continue dimming them down more?

Advice what lamp for vegging.
High guys, My Jack Herer will move soon to a closet with a 60x60 cm surface. For flowering I will use a 180 watt Hans Panel. And I do have 2 led lights at home for vegging. My first option is the Spectrabox. And my second option is the Cree Cob led. What is my best option?

Bloom light on heat goes too high?
When turning on the bloom setting the temps seem to be getting up to 84 on the very top of my tent and around 80-82 by the bud sites. Is this too high? Is there any problem turning the bloom high power switch off to let it cool down for a half hour once or 2 a day if too hot?

When to lower light intensity?
When is the right time to lower light intensity? I'm on 5th week of flowering, should I keep my lights on max or reduce the power/increase the distance to plants? I have around 1000W of Led's at 35-60cm distance from the tops. I see no burning/bleaching or anything like that.
