Is my plant showing signs of Nitrogen deficiency?
CornerBudstarted grow question a year ago
Autoflower, day 40. Most leaves are in a yellowish-green tone or even completely yellow. I was mistakenly watering it with tap water, but when I noticed the yellowing, 1 week ago, I started watering with mineral water at pH 6.49.

Are these pictures from the bottom? Is it generally stealing the nitrogen from those bottom fan leaves to enable new growth?
If it’s green at the top and mostly yellow at the bottom then yeah it’s N.
Also I don’t know how old your plant is but don’t forget towards the end they are essentially dying so expect lots of shed leaves anyway and weird colours.
If your mid grow and it’s yellow nearer the bottom than top then yes is nitrogen.
It’s a mobile nutrient so it can be moved around the plant to where it’s needed if there isn’t enough. Hopefully this helps mate - iv literally just been through this the past week or so coz I left em over Xmas! Mines returned to normal now. Took a few days…

Bleaching evenly, for sure lack of nitrogen. I would bump all NPK. N part for few weeks is still needed. Then you can concentrate on PK boost.

It looks like there hasn't been enough Nitrogen through veg and now it's using all stored N from the leaves. I'd be tempted to add a little bit more N to your bloom feed for a few weeks. That is what I see from your diary, wait for more growers to chime in with there thoughts incase I'm completely wrong.

Your tap water is probably fine if it's not going through a salt based softening system. "Mineral water" is just water with at least 250 TDS, aka "hard water". I guess you're using some sort of fortified soil mix, those can be tricky to blend to the right strength and it's easy to go too hot or in your case a bit too light. The N got depleted a little early but you also probably don't have much stretch left judging by the progression of the flowers. If you have any of your mix left, you could top dress it a little otherwise you can probably ride it out.

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

Fast yellowing in older and middle leaves, small buds.Hi guys, I need your help on this one, this is a completely organic grow under a FC-6500 light which is 60cm at 100% power, it can't be light stress because the tops are fine.This yellowing happened fast in the span of 4 days.PH shouldn't be an issue since I calibrate regurarly.
