HELP! UNderfeeding or headed to lockout?

[DJsublimeATLinCO]

Is the yellowing I’m getting from over or under feeding? I’m running advanced nutrients (yeah, I know) sensi bloom A&B, b-52, big bud, carbo load and over drive. Im feeding at 2ml/liter on all. I’m on a FFW schedule and on water days I’m adding cal mag and Pure Blend Tea. Ph is between 6.1-6.4 going in and 5.8-6.4 coming out. Ppms are currently 950 on feed days and 380 on water days. Growing in Pro Mix in 5 gallon pots.

Last run I had 3 nite lockouts so I’m being extra cautious this run.

Definitely looks like defincies to me. They need to eat. pH seems to be fine. I would up your ppms on next feed. I just fed my 57 day old plant over 1000 ppms and its still in veg. You should be fine to up it a couple hundered.

Thank you!! I was hoping it was that and not lock out.

 

[UrbZ]

Not 100% someone else should jump on and confirm or rebut. But thats what its seems in my opinion.

Was told the same thing by a grower here in Colorado. He thought it was underfed, as well.

I don't see how they could be underfed with all your giving them, I use advanced nutrients too, an mine ain't never turned yellow like that, an all I use is 2ml a ,what kind of light are you using ?

 

[DJsublimeATLinCO]

4x1000 hps. What do you think is causing it?

 

[UrbZ]

Could be light burn. What size grow area and how close to canopy?

 

[DJsublimeATLinCO]

It’s a 12x20x7 room. Lights are 28-30inches off the canopy. Canopy temp is between 76-82degrees when the lights are on and 60-65 when lights are off

 

[UrbZ]

That all seems fine. The plants look good other than the coloring. No leaves show any curling anywhere?

Do you have any earlier pics before flower? Like late veg or preflower stage.

 

[DJsublimeATLinCO]

I do have some leaves that are twisting.

 

[DJsublimeATLinCO]

First pic is the twisting leaves. The rest are 5 days after flipping to flower.

 

[D.A.A.S.69]

Those plants look bleached to me, but I don't know how, it sure ain't from being under fed. That's plenty of nutrients.

 

[DJsublimeATLinCO]

I’m doing some light trimming (day25 flower) and just trimmed this leaf. Pale green on top and mostly red underneath

 

[UrbZ]

Red is phosphorus deficiency usually especially starting at the bottom of the leaves.

 

[D.A.A.S.69]

Cool weather can turn them purple red too.If he's feeding that amount of nutrients it's no deficiency

 

[UrbZ]

You think maybe rootbound?

 

[UrbZ]

can you share a pic of the whole set up?

 

[DJsublimeATLinCO]

First one is toward the front. 2nd is toward the back.

Sulfur deficiency?
