Epsom salt foliage spray

I mean correct me if I’m wrong but everything about this picture scream’s magnesium. Bottom leafs yellowing in between veins etc. although it could be from a lockout from my understanding a lockout it only in the roots and wouldn’t effect the leafs up taking nutrients therefore a epsom salt spray seemed necessary to me. If problems consist then I’d lower my ec and see if that’s the cause.

The reason for the Calmag really wasn’t because I thought they needed it but because I’m using RO water so as a buffer.

Definitely looks like Mg deficiency to me. Maybe a little K deficient too. I'd be temped to feed them more. Intense lighting makes them hungrier. If you turn the light down they won't need as much food, but I'd feed them more and see if they like it first.

What nutes are you using anyways?

You also didn't answer the question of how often you're watering.

Meant to say .2ec sorry lol and I water twice a day until I get about 10 to 20 percent runoff.

Which makes sense because magnesium effects k right?

PadawanWarrior said:

Too much Mg will lockout K and vise versa. Ca is also antagonistic with Mg and K.

K and Mg deficiency also looks kinda similar. It kinda looks like both to me, but more Mg deficient than K. K deficiency usually starts at the edges.

A lot of people add Epsom to their feeds too.

I know a bunch of people that had a system for feeding and when they got intense LED lights had to bump up the EC.

Thanks for the reply man I was thinking under the same lines as you but didn’t even really consider bumping my ec up much appreciated, I’ll bump it up and give it a foliage spray tonight after the lights go out and see how it goes. You think I’m all set with calmag as someone else suggests? My only issue was I thought ph would be running all over the place in ro. My honest opinion was that I thought with the led lights and being in coco with ro that my plant was up taking calcium faster causing the mag deficiency.

I don't know what nutes you're using or what it has. But if you're using RO water you might need it. I don't know.

Yes a two week old plant needs more than 1.1 EC. Explains why your plants look the way they do.

Also I do appreciate your advice I’m sure you know a shit ton more then I do but if I took everyone’s advice on my plants then my ec would have went down then way higher then my lights would have been lowered in power while spraying the shit out of them. I did note everything you said. As I said above I’m still learning and want to grow the best meds I can. I’m sure your garden looks great much love.

You're taking advice from the wrong grower, he doesn't even use coco. You're already at 1.1 EC, two week old plants don't need more than that.
