Is this Nitrogen deficiency?
Is this Nitrogen deficiency? Mainly the lower leaves colored light green into yellow and just burst off. Now a few bigger leaves thought the plants are following the same pattern.

Brown/yellowy Spots and Stripes
Alright, last night I did a reservoir change. I added a fraction more nutrients to the water (.25ml per gallon). I also topped the plants. This morning I woke up and there were these brown/yellow spots and stripes on the leaves. Any idea what itβs from? Thanks!

Yellow bright new growth
New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?

Lower Leaves Yellowing
I have noticed that a lot of lower leaves are turning yellow. Theres nothing special going on, it just fades from green to yellow evenly. I am feeding it Veg nutrients 3:1:3. So it can't really be a Nitrogen deficiency right?!

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?
Everything was well, until over just a few hours they developed all kinds of symptoms. I have 2 diaries here for the grow, the 2 called βGrow #2β and I am very detailed about what has been done day to day. So please have a look and see if you know what might be happening

1st grow yellow leaves and brown spots
Last two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(

Can anyone tell me what's going on in week 2? I transplanted and each plant seems to be yellowing on the lower leaves. Not very happy. Was dry when I took it out of the dixie cup and watered with 1/4 strength veg nutes and a root stimulator. It seems to be curling in as well.

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.
