Hey! Your lights are even set very high, so that's definitely not it. With too much nitrogen, your leaves would be much darker. It seems to me the most like number two, calcium deficiency. Your nutrients also seem a bit low to me. Check out a feeding schedule (normally this is at week 5 at 8ml per liter (a+b nutrients)). Now that might be a bit too much of a good thing, but I would still increase it a little. Check your pH level so that all nutrients are properly absorbed. I hope I can help 🙂 Good luck! 🌱

This is a calcium deficiency all the way dude. Haven't checked your diary specifically so the general answer is to get yourself a calmag supplement. Botanicare, Cali-magic, either will do. It's only ever really needed when you see this issue so good to have it on hand. Feed as part of your solution at 1ml/L. If everything else with the plant looks good and this is all you're seeing don't change anything else. She'll be fine regardless and the addition of the calmag will clear this up within a week or two. Good luck with it - NL is a personal fave!

I have some yellow spots as can be seen in Week 3 Day 20 pic. I am not really sure what it is or how to get rid of it. It appears to be on lower few nodes but not upper one so far. It is not affecting other plants in tent at this time.

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

Brown spots on Day 5 I have noticed some little brown spots on the leaves of my PPV. Can anyone help me out with what they might be. I am day 5. I probably saw them slightly on day 3. PPV is pretty hardy so should I just chill and wait and see?

Spots on yellowing leaves Brown spots on dying yellow leaves. This has happened on most of my plants after budding so thinking it may be a soil problem. My guess is boron, manganese or phosphorus as the stems on some plants are red. It starts low and eventually ends affecting buds too so I chop.

Am I right that the brown spots on one of the plants are an indication of calcium and/or magnesium deficiency? I ordered some CalMag Extra from Advanced Nutrients; should arrive soon. Would/should I apply this only one time or add to the regular feeding schedule?
