Looks like it has a little heat stress, but still very healthy looking for being in high heat all week.

Yes light heat stress but nothing to worry about. Mother nature has always taken care of herself outside.

Weird Curls and Holes
Okaaayyy so wtf 😂 I've altered light intensity and height multiple times at this point. I've ruled out pests. I think it's either windburn, heat, light, or a combination of all 3. It's a little concerning seeing as how I think mid flower is right around the corner 😓

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

Are my clones infected with HLVD virus? can this be reversed or should I throw everything in the trash?
I bought 12 clones from a grower, two grew slowly from the beginning. after transplanting, this "disease" appeared on two pieces, and now I think more have caught it.

PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)
TS1000 (150W x 2), set to 75% at 12-14". "Photone" app (yes, not as good as a PAR reader) reads 580-700 PPFD, so I sense these girls aren't getting as much light as they could. I've read that pushing 900 PPFD is desired (CO2 bags);fan leaves curled. How should I think about this?

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. 😀

Curled leaves
Why my plant's leaves curl up like that? I think that there's an overwatering issue, but is there any way that my soil is not good?

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。

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?
