Бро, это недостаток влажности и точечный нагрев на листе 29 и выше градусов, я заметил подобное явление при тестировании матриц смешанного спектра (малинового, розового цвета) там где были ir светодиоды, при использовании фокуссирующих линз на молодых растениях такое наблюдалось, на цветении не так заметны подкручивания, но это точно стресс - световой, температурный - скорее всего. На стадии вегетации использование не очень мощных ламп 6400-3500k без ir диодов - не вызывало скручиваний листов.

In your case it’s seems that it’s a lack of humidity as your level is only 55%.

This is a 27-day auto plant. The problem is that the leaves are crunchy and curled upwards. Soil pH measurement 6.5. There was a fan right in front of it, I changed its direction 1 week ago. Do you think this is a disease?

Minor Leaf Curling? Over Water or Over React?Well my plant has been doing great and very much still is to be fair. But ive noticed some curling starting on my leaves. Is this due to over watering possibly or is it too hot in my grow area or am I just over reacting? Thank in advance!

Tips of leaves turning (again..)Why are the tips of leaves curling up again? This is happening only in one plant. Other plants are looking very healthy, this too but the leaves are just playing around. pH and EC are right and it shouldn't be too hot.

我的女孩怎麼了，這個是生病了嗎？還是太多的餵食？在他長出第二對葉子的時候這樣的現象就出現了，但是只有一邊有葉子，我查了相關資料顯示這是菸草鑲嵌病毒（Tobacco mosaic virus；TMV）我覺得挺像的。但是不是很確定，我該繼續等幾天嗎？還是把葉子切掉。誰可以告訴我解決方法，希望他可以度過生長期，因為他是自動開花，每一天都很重要。

Not sure what is going on with this Fastbuds Crystal Meth The week has finished, and the plant doesn't look very healthy. Although it has been growing quickly, new and previous leaves and curling up. I am not sure what kind of deficiency or excess is this. Should I kill it and grow a new one?
