Any ideas what’s going on

[Cousinbob]

Plants were healthy until I moved them across the room to this tent with my LEDs running CO2 at 1000 ppm and veg been giving them about 800 ppm nutrients that have been fine the whole time until lately as they’ve been getting a little older have other plants that are even larger they are getting the exact same treatment and doing fine

Need more info on grow

Nutes
Lights
Temps
Rh
Medium used
Water
Ph

Also CO2 use is kind of moot if not in fully sealed grow area and are exhausting air.

Floranova veg roi e680 led about 80 degrees fb around 40 promix hp medium ro water 1/2 teaspoon per gallon of cal mag plus with nutrients and recharge micro every so often ph 6.4 room is not sealed no exhaust

I believe I see early magnesium deficiency.

I don’t understand they been getting same treatment and was fine sometimes even giving 1100 ppm they are in 1 gallon bags and about 1’6” tall

Maybe up the cal mag plus to a full teaspoon which I have feed them before

I would bump ph up ... ( 6.5 + )

I can try but there in pretty bad shape for only wanting a few points of ph

 

[Budzbuddha]

Doesn’t matter on “ same “ regiment ... as EACH plant will feed on its OWN terms. Something is getting locked out

You need to match range of medium for it to make ALL elements available. I would bump to 6.6 / 6.7 to allow for drift.

Plus ... in led grows leaf temps need to be higher for proper uptake

in not exactly sure, but he's in promix. Isn't that more like hydro than soil?

 

[Budzbuddha]

Peat based as many bagged mixes are ... usually around 6.3 from bag so a range around 6.5 to 6.7 is s good range fir plant to pull all available nutes.

Ok. I've never grown in it. I've just seen arguments that it's "hydro not soil". Lol

This was exactly what I thought when I first saw the leaves. I've had a magnesium deficiency and this is exactly what it looked like.

It's soilless but it's not hydro.

Right...I get it. I know it's peat and I know it's a soil base. I just wasn't sure if it's more like coco.

Those big plants are only in 1 gallon bags?

Leaf temp ?

They have got 6.5 few times mostly 6.4 I’ll try raising ph some

Yea I’m transplanting this weekend
