Calcium. Don't know why - there are several causes and therefore several remedies - but it's lacking calcium. Again, please start a diary.

Could be septoria. Hold it to the light and see if there's orange or a glow around the dots, could possibly be bugs.

Tips turning yellowThe tips of the leaves are getting yellow. What does it mean? And what can I do about it?
I just replanted her a day ago. No nutes since then and not much before that either.
I attach two photos: the first taken today and the second - last week.

Yellowish color at the tips and wrinklesMy plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

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.

Weak yellow leaves with red StemsWeak yellow leaves on the bottom with red stems. I use 1/3 tap water, 2/3 filtered water for its pH levels. Could that be my issue? I feed twice a week Fox Farm Big bloom 2ml/l, Grow Big 2ml/l and Cal/Mag 0.5/l. Cal/Mag with every watering to make up for the soft water.

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. 😀

Growing in FFOF with some HF but have nutrient issues...have only given CalMag with RO water and this is what I've got.Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?
