Why are the leafs on my plants getting dark green ...
MadBumbleBeestarted grow question 5 years ago
Why are the leafs on my plants getting dark green instead of a light green?
Is it because of the strain or nutrient lockout (nitrogen toxicity, too much potassium, too much phosphorus?) or perhaps not watering enough?

Check your leaves. If they are curling and/or clawing it's nitrogen, look for it in the Newest growth. If your leaves are shaped "right" then it is not nitrogen and they are just dark.. Without seeing nice and clear pictures of a "problem" plant it's very hard to tell unless they are suffering badly. From what I can see they look totally fine, if there is clawing/curling it's only minor. You don't even need to cut the Nitro out altogether you just go lighter on the feedings if they indeed have slight toxicity. Lots of growers just do very "light" feedings every time they water. The plants need the nitro right now and will eat it up just don't wanna oversaturate them, if it is indeed a case of slight toxicity. You are in Great shape really if it is a nitro tox, you've got plenty of time before flower so you can really get your plants dialed in before you flip :). I hope this helps if you need further information please pm me I can help :). Happy growing.

they get shiny and dark green from the extra N, the purple reflection is from the lights i'm quite sure. So it's a question of N, probably a bit too much, nothing to be worried, just cut back on the feeding, in soil you dont need to feed every time or even every week. Double check to see if you're giving N in your cal mag or sometimes there's extra N in various feeds. You'll want to feed, then give plain water twice, then feed again, then plain water the next two waterings and so on. Hope this helps ! 🚀

Generally dark green foliage means Nitrogen toxicity , also most of the sativas I've grown were tending to be dark green during the vegetative stage

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Catching a fade?Is this fade normal for a Crème de la Chem? Or is this some other kind of deficiency. This plant has not had any issues. She’s the most healthy of all of them. In the pics I’m trying to illustrate the purple color showing up on some leaves.

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.
