Yeah I agree with roberts, looks like a few deficiencies happening.. I see some nitrogen and magnesium deficiencies from the yellowing as a whole and interveinal yellowing/browning Like roberts said, a pH issue could be locking out nutrients

Looks like a mix of things going on. I would guess a ph lock out. Check substrate run off ph.

What’s Happening Here With My Leaves?
Not sure what’s going on here. It’s happening to 3 of my plants and I’m not sure whether its good or bad. I haven’t watered in 3 days so I don’t think it’s overwatering because it just happened today.

My plants are 3 years old (counting from soaking the seeds) and they are growing really fast but the leaves are a little bit yellowish in the middle. Is this some kind of deficiency or maybe something else? I’m a newbie to this and need your help guys ;)

What deficiency this is ?
Perhaps in these pictures you can see better, what deficiency this is, whether it is phosphorus, potassium, magnesium or zinc?.

Leaves are turning yellow from the bottom up and I'm not sure if it's the natural death of unessery lower leaves or a nitrogen deficiency. It's not a ph problem. Thoughts?

Sénescence ou manque d'azote en phase de floraison.
Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

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

Can I use magnesium sulfate foliarly?
Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.
