Leaves Curling Up and discoloration in the Middle of leaves
Papa_Tanswered grow question 4y ago
I read your diary. The leaves discolouration I think is due to a slight magnesium def. I would make an epsom salt foliar spray at 20-50 PPM adjusted to 6.5 PH.
Spray that onto the plant just after lights out so your plant isn’t wet under the lights and gets light burn from droplets. This should clear up your issue.
I see you’re in soil. It also maybe time to start supplementing a bit of cal mag into your feed regimen.
Hope that helps. Cheers 🤙

Yellowing, curling tips?I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake2y ago

Why are leaves curled?Im a little bit freaking out about those curled leaves, don't want to fuck up Another grow.
I figured out on my own that i have small magnesium defficency added 0.1ml/l calmag.

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。

Do I have an (Mg) issue?Leaves turn light, have black spots and 1 leaf rolls in upwards. It got Epsomite with every watering so I guess it's not a deficiency. Last time there was not even a drain. So maybe nutrient absorption is blocked? Should I flush? Is it to stressfull for this autoflower?
