Not light stress, but the beginning of magnesium deficiency. Giving cal/mag will solve this and prevent it from getting too much worse.

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10
This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!

Should I substitute sunlight with a grow lamp on cloudy days?
It’s overcast here today and I’m wondering if I should turn my grow lights on to compensate for the lack of direct sunlight. If so, should I drop the intensity to compensate for the additional natural light? Can you overdo the amount of light (not heat) a plant gets?

Light Burn? Mars Hydro TS3000 at 30% Power, 26 inches away per manual. I have since raised back to 30 inches.
Is this light burn? I noticed some slight yellowing/crispy looking leaf at day 11. Light is about 30% Power, about 30 inches away. I previously had it about 26 inches and raised when I noticed this issue about 24 hrs ago. Pics are updated. Temps: 70-75 RH: 50-60 Soil Runoff: 6.5

Yellowing leaves and nutrient lockout. How do I fix this? This has been a long time problem. Definitely overfed for the first 3 weeks of flower.
Lemon Cherry Cookies locked out for weeks. She's yellowed up big time. Took in less than a quarter gallon water yesterday and a half gallon today. But then she had a higher EC and TDS before adding plain pHed water both days. After topping off it went back down. Check my diary.

High guys, My Jack Herer will soon move to another closet. I've got 2 led lights at home for vegging. Both use 60 watt but have a different colour spectrum (only have space for 1). Which one is my best option FOR VEGGING ONLY!?!? My options are the Spectrabox or the Cree Cob.

Light help please :)
I’m trying to figure out the optimal height to hang my KingLed 1000w full spectrum at for seedling, veg, and flower. I feel like part of why my plant was is so small is due to incorrect hanging of the light but idk

Light power
Is a 100-watt lamp sufficient? I don't consume much, so I opted for a modest light, anticipating lower yields. Can the quality match that of weed grown under a stronger light(600watt), despite producing fewer grams overall?

Light burn or nutrient burn?
Hey guys. The tips of my leaves are starting to turn yellow and I’m wondering if this is a nutrient burn or light burn? I lowered my ppm feeding to about 250 a few days ago and am growing in ocean forest fox farm soil. And the light is an optic 2 running just the cobs at 24”.
