A shot of cal/mg would do her some good. It's also high in nitrogen.

I found one leaf that has some serious problems (Day 72 last picture - single leaf). We have to weeks to go and I do not panic. But I wanna know if this is a problem with anything or just their lifespan. Many leafes under the Kind LED feel very dry and burned but look different 😕

Nutrient deficiency, pest or under-watering?
I'm not sure whether i'm having a nutrient deficiency problem, am under-watering or having a pest. As you can see some leaves dried up and turned yellow and i'm also noticing a little bit of interveinal chlorosis.

Leaves Showing yellow edges and banding
Is yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?
Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl. Does it look like heat/light stress to you or something more? I was running my LED 45 cm below the lights dimmed to provide 20-30k lux at plant level. Just now raised to 65cm, lux 20k.

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH

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。
