Some new leaves are getting yellow/weird. Do I need to worry?
Hi guys, from today some of new leaves are growing like this. Is everything regular or is it a sign of something wrong? Given my inexperience I don't understand the symptoms from the leaves. Info: DWC - 42 days from germination - PH 6.0-6.4 - EC 1.5 - Temp: 29 - RH 60%

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. 😀

Plant seems to be dying, should I flush? And if so, any tips?
Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.

Grayish brownish fuzz on sugar leaves
Turned my northern lights plant around today and noticed this on the back of it. Yikes! Is it bud rot, pest damage, something else? If it's bud rot I need to get rid of it ASAP because I have 6 other plants in the same grow room.

Meine Pflanze zeigt aktuell leichten Kalium Mangel. Aber irgendwie nur auf eine Hälfte der Pflanze. Die andere Hälfte sieht gut gefüttert aus. Kann mir das jemand erklären? Also warum betrifft der Mangel nicht die komplette Pflanze?

Yellow leaves question.
Good morning growers, I have noticed some yellowing of the bottom flowers on my one of my plants. Everything else looks extremely vibrant and healthy. Does this look like a watering or nutrient issue? Or is it something I should not be too concerned with ? Thank you everyone :)
