yellow/dark discolouring of leaves late into flower
Noticed this on about 5 leaves, some more affected than others. The plant is towards the end of the flowering, with about 3 weeks left, better to ignore it now or try to do something ? perhaps leaf Septoria, already increased air flow and decreased humidity

Nitrogen deficiency or could it be nothing
In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Bottom leaves lifeless and yellow
Hi! My plants are in their 2nd week of flowering and some of the leaves at the bottom of the plant (very few in the middle) are starting to turn yellow and they look kind of lifeless. It's very dense in the tent so maybe they don't have enough light? or lack of nutrients ?

Sénescence ou manque d'azote en phase de floraison.
Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏

Yellowing leaves help please (newbie)
Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

What's up with the yellowing leaves? They seem to yellow from the outside inwards and the tips also seem burnt too. Is it nutrient burn? Excess or Deficiency? It's mostly on the bottom but its affecting some of the bigger leaves in the middle too, Watch the video for an overview!

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Ongoing brown and yellow patches forming in week 6 of flower
I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

Slight Yellowing on tips of new-growth? (VEG)
Why am I getting slight yellowing on the ends of new-growth leaves? It's affecting every plant. The only clue I have is that it might(?) be related to very cold nights because of my re-vegged photoperiod showing purpling on the edges of its leaves. Any ideas?

Plant starting to yellow too fast
The crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?
