1st plant. Seems stunned and yellowish with black dots tips. Can anyone give a hint?
Hey, guys! How are you doing? This is my first plant. It is 4weeks old, planted on cocó-perlite mix. I find it growing too slow based on other diaries, and it is starting to show these yellow with black dots tips. Anyone can tell me what’s going on?

Lack of water or its something else.
Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄

Leaves are turning yellow and dieing. Looks just like nitrogen deficiency. I'm in early flower
Losing a bunch of yellow leaves during early flower. I have WPM but it wouldn't progress like this would it? I think I may have just been underfeeding or my pH is off. What do you guys think?

Yellow on Cotyledon normal?
Is that yellow on the cotyledon leaf normal? 2 days post sprouting and that one had helmut head the first day. I was able to remove seed pod by lightly lifting the edge of it with tweezers.

Why are my leaves turning yellow?
I have stopped giving it nutrients since I was seeing potential nutrient burn. However, I am still seeing some yellowing in leaves, some leaves also have yellow spots. What could be causing this? There might be some white flies in the tent.

Желтеют листья.
Всем привет! Выращиваю первый раз, сорт Auto Opium, растению месяц, нижние листья начали желтеть и вянуть, это связанно с переходом на цветение? И за какое время растение будет готово к харвесту? Заранее всем спасибо за ответы😄💚
