Heat stress causes rapid evaporation, so plants curl up to conserve moisture. Plants too close to high-intensity lights are prone to heat stress, but it can be a problem in any room where temperatures are persistently above 80 degrees F.

Mutation?
Hey all. I planted 3 Bruce Banner seeds 8 days ago. They sprouted from the top soil in 3 days. Super fast, but they look a bit strange. They had leaf twisting from start and now they're showing some spots. Is this a mutation or did I not flush the reused medium enough, so burnt?

Leaf mutations in Northern Light Automatic (RQS)
Hello. Could this leaf mutation in Northern Light Automatic (RQS) be dangerous to the plants? What could it be caused by? Could this be caused by too much light for the sprout and the Top Crop Green Explosion fertiliser? The leaves grew very strong in a few days after fusion.

Yellow marks in leaf center and weird King Kush?
There seems to be some yellow marks developing in the center, this tends to be on the outer side of the leaf, especially during over/under watering? Could this be calcium/magnesium deficiency being that the water source is from reverse osmosis? Also, any thoughts about the KKush?

Toxicity, overwatering or deficiency? What have I done wrong?
Hello there, beginner grower here. My plants are now in week 6 veg and have been looking amazing the past few weeks. As of yesterday, they all look a little sad. I watered about twice a week with half dose of BioBizz organic fertilizers. Thanks for your help

Seedling with leaves struggling to open and slighly curved upwards
I'm seedling two Super Lemon Haze Auto, but one of them is struggling to open their leaves. They are slightly curved upwards and without the shape of a normal leave. The other plant is growing fine, and I'm watering them with the same nutrients. Any tips on what can be happening?

Leaves are firm but dropping flat, pointing downwards. Over watering? Diagnose and recovery advise?
Would appreciate some input into the possible over watering issue? Her growth definitely seems stunted. Growing in a 46l fabric smart pot, with bio bizz all mix. Finding it difficult to diagnose the issue. There is general overdosing at work also? How to recover?

Strange Growth
I’m having some kind of strange growth on the 2 FastBud babies. The Blackberry Auto seems to be okay. If you look at these 4 images you’ll see the difference. Any ideas? Note they’re all in matching soil, and I’m rotating them under the lights every 2 days.

Curled leaf
I'm not sure what can this be. Any ideas? It's just this one that got like that. Should I be worried if it propagates to more foliage?

This plant looks terrible ! Never saw that before... Please help
My Dark Devil Auto looks terrible. Leaves are not healthy and I ignore why... Temperature is always between 26°C and 29°C, but 29°C is very rare as I try to always lower temp. Humidity is between 50-55%. Royal Mix from Plagron and LITTLE fertilizer. (Root/grow/humic fulvic acid)
