Looks like a magnesium deficiency to me. Some of the pictures from last week it looks like there is some interveinal yellowing and the deficiency has progressed. Epsom salts will help fix the issue. Happy growing!!!

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 “Grow #2” 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

Is it infected?
Is it infected, like mildew, or has it just some nutrient problems in the beginning? And the leaves form is just the genetic i guess?

Strange spots in leaves, help PLEASE
Please, HELP. I don't know what's happening with these strange spots. Her growth is pretty good but I'm worried. Lights at 60cm. Nutrients, Temperature and RH are theoretically ok. I've even enriched it with worm humus a couple of times. Her sisters are really good all of them.

Hello, I just noticed that some of my leaves are starting to have slight discoloration and some holes. See images in week 6. I don't see evidence of bugs or mildew and my fan may have been too close for the leaf with holes. I feed once a week and have switched to a high K feed.

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10
This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!

Hydroponics, i need a second or third pro opinion. Just a Deficiency? bad pH? (I alreadt did a partial water reservoir change tho)
Yoyoyo! If someone of knowledge could help me here, I would be grateful So I think it's a Magnesium deficiency, caused either from my too low pH (5.2) or too much CalMag (only used 1,5ml on 10L) I gave a more in-detail description on my diary. lower leafs are "crispy", not smooth

So at day 55 I'm noticing that some of my leaf tips are looking a bit burnt and some rust colored spots are showing up on the leaves. I read that this might a deficiency of cal or mag or a ph issue. Just wondering if any one could help my diagnose this issue and try to fix it.

Brown spotting?
Hey everyone! My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean? I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.
