Hey,
Just by the pictures, I'm guessing your ph is a little low. This will cause calcium, magnesium, zinc, and iron to be locked out. Make sure you're measuring the ph of your runoff water. Pm me if you have questions.
Cheers,

It could be a lot of things, without any info on what they are being fed/how much/how often/ temp/ humidity/ etc. its harder to make an accurate diagnosis.

Discolored Older Fan LeafI’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?

Vexatious yellowing I can't get to correct.This Northern Lights auto is being vexatious...I can't get rid of the yellowing towards the bottom. Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.

Yellow lines on 2 leavesAny clue what this is? About to be week 6 and in flower. I'm thinking the start of nute burn? I gave it bloom boost in the last 3 waterings in less and less amounts. let the soil get very dry before watering with plain 6.2 pH water. Any input is appreciated

2 Yellowing Fan LeavesI have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges.
It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant.
From research, it could be the bump in nutes or water issue.
Any ideas?

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?

Yellow/ brown leaves #2 (pics didn’t post the 1st time)Hey guys so my plants are starting to turn this yellowish color and I’m not sure what the problem could be. Sorry for the second pic, it’s kinda blurry but that’s the actual color compared to the other leaves. It’s my first grow and I’m kinda lost on a solution . Many thanks

Rapid yellowing of some leavesI've noticed strong yellowing of some leaves overnight. It usually happens to the lower leaves, but in my case the whole plant is pretty flat, so there's no real distinction between lower and upper leaves. Is that just flowers taking up nutes from lower leaves or some deficiency?

Deficiency/Light Stress IssuesWhat else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Yellowing leaves, why?Her leaves started to yellow, probably because she was dried out for one day, so I watered her properly with 1.5l with 5ml of biocanna flores(first time). After 3days I would expect her to be dry again, but the soil is still quite moist. Why is she drinking a bit less?
