possible light burn help me tanx
Nurse
started grow question 6y ago
I have two lights, spider sf 1000 and viparspectra p1000. My plants have burn marks. I do not know if it is from lights or fertilizers. I now keep them 18 inches apart. Can anyone tell me the light distance table? How far should they be now?

Can't see much wrong. Not all leaves are 100% perfect, 100% of the time.

Efficient lighting
Keeping both 200w VEG and 300w FLOWER lights 24h is too expensive for my alien wallet. So I left the veg light under 12h/12h and flower on. Please share with me some of your past experiences and how can I save money and grow killer yields. 👋👽

light bleaching
Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

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

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.

Has anyone watched some Youtube videos by Dr Bruce Bugbee from Apogee Instruments? I find his lectures on lighting to be the most straight forward explanations I have heard yet.

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?
What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?
