Not sure what this is.

[ZioNLioN87]

Hey,

I've tried comparing my leaves with pictures but I'm not exactly sure what the problem is. I've had the problem before and I just thought it was nitrogen so I added veg nutes. It didn't help at all and the yield was really low. My PH is always ok.
Cheers.

when asking for problems on plants please provide our users will all information about your grow set up
think of diagnosing plant problems are a puzzle, if we only have 1 piece to the puzzle there can be too many variables, it can also be harder to tell what is actually wrong with the plant

if you provide us with more information we can best than determine what is wrong

please advise users of
lights
set up
grow medium
nutrients (what type,/brand)
water schedule

etc.

I'm running 4 x 600watt HPS
My plants are in soil in autopots. Not too sure what the brand is, it's a light mix so there's not really any nutrients in the soil. I'm using vitalink earth bloom, and buddahs tree PK. The plants have around 4 weeks left. The pots are constantly in water but they have a layer of pebbles in the bottom.
Let me know if you need anymore I formation.
Cheers.

Also, what part of the plant are those leaves from? Are they at the bottom? Are all the leaves like this, all over the plant?

I would say mainly the lower half of the plant but there are random ones higher up.

Would be helpful to post pics of the entire plant. There may be other subtle signs in the plant that can help someone diagnose the problem.

It's a bit hard for me to get an individual plant to take pictures of.

I have 16 and its happening to about 14 of them. They look worse today with a lot of yellowing leaves.

Do you think this looks like a manganese deficiency?

 

[pseudobotanist]

Turn off the hps. All I can see is a yellow hue

 

[ZioNLioN87]

Are these any good?

 

[hotrodharley]

Have you been giving micros? Have you given some nitrogen through flowering?

 

[pseudobotanist]

I want to say either phosphorus or manganese issue

 

[ZioNLioN87]

I haven't given them any micros and the only nitrogen they have really had was in the flowering feed.

Would superthrive do them some good? I was thinking some superthrive and some veg feed.

 

[pseudobotanist]

Don't use super thrive. I'd start at 1-1-1 ferts and see how they respond. It's yellowing from the middle of the plant on up or from the bottom?

 

[ZioNLioN87]

Looking at them now it seems to be from the middle up. I've got some major yellowing going on.

Just incase anyone comes across this and has a similar problem.
I used some Canna mono Trace elements and it worked like magic. Everything is now pretty much green again and growth has continued.
