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

Fertilisershello! I'm using a prefertilised substrate with NPK 12-14-24 (Plagron lightmix).Which nutrients should I consider to buy next?
Plagron offers a NPK 3-1-3 or 4-2-4 for growing and a 2-2-4 or 3-2-5 for blooming. Beyond brands, what ratio should I look for, for what elements?
ThanksWeek 2

Is Co2 enhancer worth itHey have any of you guys used the co2 enhancer thing they sell online or at some gardening store. I know for sure it can do a difference in veg phase but growing hydroponically and growing auto already gives me fast and strong vegetative grow so should i even bother?Week 2

Diamond black vs. Diamond nectar by GHEHi everyone,
I've read Diamond nectar is very good. But I noticed there is a very similar product from the same brand: diamond black.
I was wondering what's the difference, and which one would be the best in an indoor grow in coco with high frequency fertigation.

Why is my PH possessed?Why is my PH refusing to go down from 9s to 6 unless I quadruple the normal amount of apple cider vinegar to 12ml? Normally 3ml does the job. This week, ml somehow doesn't move the needle. The EC is a little higher, could that be it? The RO is normal starting at 8, this week 10+Week 6

I'm really happy with buds, but the smell is a little less intense that I would like.

FOAM in the DWC tankHi guys, yesterday I changed the solution in DWC and today I saw some foam in the tank.
I had some ph oscillation and used first ph down and after some silica to raise ph. I guess that could cause that foam, what do you think? Some tips?Week 4
