If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Warum werden die Blätter auf einmal so schnell gelb und welk?
Hey, my Hawaiian Runtz is at the end of week 4 of flowering. I water every 4-5 days with 2-2.5 liters of water and a pH value of 6.5, always pretty consistent with Terra aquatics pH drops, so pH errors should be ruled out. Temps during the day are around 28 and at night 26 degrees Celsius. What’s wrong?

What is happening to my plants?
I had them in the terrace outdoors. Temperatures sometimes reach 40C. Lately more and more yellow leaves in the ABC have been showing up. In the other normal leafed plants crispy dried and brown leaves are showing. Now the ABC also is showing some dry leaves and yellow as well.

Some advice for the newbie please! Yellow spots on the leaves.
Crushed Seashells in with the medium for calcium.Been spraying insecticide the last week. The last 24hrs I have cleared some bushes around her, could an extra 3hrs direct light cause this? I am watering 2ltrs of water every 3 days.

Pin the tail on the deficiency
Some yellowing that developed on Gelato Auto in the last coupla days....my guess is nitrogen deficiency since feeding has been light throughout growth but I'm still new to the game and would love to hear from some more seasoned growers

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Yellowing plants
Based off week 2 day 7, does this look like an over watering issue or something else? This was the first watering where I soaked their containers. While they were in solo cups I tried to keep watering volume low.

Auto flower deficiency
Hello I have a auto flower I grew in soil from last year. I believe this is a nitrogen deficiency but not sure. This plant is 37 days old and 1 week into flower. How can I fix this? Cal-mag? Worm poo? I'm not sure.
