Light Stress
NorthernStar20started grow question 4 years ago
Had to move my plants to a new space and under a better light, can see taco type appearance to leaves, I'm assuming this is due to light stress?
I've lowered the plants and also turned the light down a little until I know what is going on.

Heya!
Could need some time adjusting to the new light. I often get those taco symptoms when the light is too close or hot. You mentioned you backed the light off a little, let the plants sit for a couple days at that height and then you can slowly start adjusting your light lower if you'd like. Just watch the plants and keep an eye out on how they react.
Cheers and good luck!

new light, maybe a drastically different spectrum? give it a moment to adjust, keep being conservative with intensity. if it stretches you know it is ready for more.

Weird Leaf ProblemNew leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!Leaves. Curl up

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is?
Please help me, I need to feed in a few hours.Leaves. Curl up

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.

Other suggestions maybe?Leaves. Curl up

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.5 months ago
