Sudden Leaf Yellowing – Lighting Issue or Something Else?
fathermichaelstarted grow question 4mo ago
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

It looks like it is getting too warm and possibly a correct amount of water. Like it's getting too dry is a possibility. Go super easy on nitrogen. A flowering npk ratio is 1-2-3.

Orange leaves getting worseWhat the fuck is going on with this plant? I spotted some nute burn last week so I got advice off here and flushed it out. Once it needed watered again I went with half the recommended nute dosage and now it looks like it’s getting worse. What the hell can I do?

Delaying Senesence?Delay Senescence in cannabis while employing a staggered harvest? Is this possible?
I'm thinking about cherry picking my top colas as they are milky and starting to turn to amber. There are also new bud sites that I wish to feed and maximize yield.

Nutrient deficiency?Dear grower,
I am having an issue with slightly yellow leaf tip. I only used BioTabs Plant Perfect Package. I am suspecting she needs some extra food, but I don’t want to over feed her. Considering giving her BioBizz Grow (little by litttle). Do you recommend this technique?
