Gassynugsgrowstarted grow question 2 years ago
The leaves look unusual and the tips are curled up. I really don't know why. Can anyone tell me what is wrong with this plant😥

That's heat/light surface stress.
You need to be applying fans so they kiss all of your plants surfaces throughout its entire grow. It helps exchange co2/on bubbles on the layers of your stomata (they're like vents, when they aren't happy. The curl up like this as a sign)

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!Leaves. Curl up

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.Week 3

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。Leaves. Curl up
