The brown spots calcium and the yellowing magnesium?I'll vote for calcium deficient
Hi Creeperpark!What kind of water are you using? What is the substrate the plant is the plant growing in?
Indeed, it's in flower as I cannot spray anythingI started foliar spraying recently with calcium made from vinegar and eggshells and Epsom salt, about a teaspoon per liter of each and also dimmed some of my LED lights a little and my young plants seem to be healthier. I was getting similar vein effect on the leaves. I grow in hempy buckets with straight coco
I don't recommend spraying buds as they can rot
Straight Epsom salts foliar spray is fairly safe to use at 1 teaspoon per liter in my experience but more information would be helpful
Soil or coco or?
Lighting?
Temp roughly?
Are the roots to wet and not getting oxygen?
Feed etc
Sounds like you are on to itIndeed, it's in flower as I cannot spray anything
I added 1 tbsp epsom salts to 5L of my water just now. Think this would be a safe amount to experiment with?
Soil, from black swallow, link to exact product & ingredients are just above!
Lighting HLG-550 LED R-spec
Temps 62-65 low at lights out
I am not sure on the roots thing, I use blumats to water and definitely don't keep them soaking wet heavy pots but they are regulated watering and WERE happy previously I *thought*!
I am a novice
Thanks again
That's phosphorus deficiency.Hi all, one of my plants has this deficiency and now the big fan leaves are starting to die or become affected, just looking for speedy advice, what do I do?

That matches my experience with the veins, I fixed it with Epsom Salt foliar sprayIt’s the pale yellow with the dark green veins … also the necrotic tissue
That's phosphorus deficiency.
The oldest leaf is most affected and damage is slowly spreading to the newer leaves, making it a mobile nutrient deficiency.
Mobile nutrient deficiencies: N, P, K, Mg.
Original
From Mulder's chart, phosphate is antagonistic to copper, calcium, potassium, iron and zinc. Phosphate is synergistic with magnesium.
Can you give a quick breakdown of what they've been fed up to now?
Deficiencies can mimic lockout. Knowing what treatments the soil has been given will help us help you.
Thanks
