Red stem

[Hugo]

Hi everyone,

I'd like to know if this is ok or a symptom (maybe phosphorous deficiency).



I've noticed it a few weeks ago first, and now after some brown burning at the lower leafs I'm treating for P deficiency.



If that stem was a symptom I could have caught it way sooner.

Thank you.

You can check more pics at my thread (shameless pub)

Red stems can also be genetic. What's the strain, soil, pH, etc.? Need all the usual info to be able to know what's going on.

Hey Hugo, I'm not the person that should go around trying to give all kinds of advice. But we have grown a northern lights auto and it's stem ended up with quite a bit of red color, and the top of the main cola even turned pinkish/maroon. She had small color all over really

6.0 is a bit low on the pH and is probably causing a bit of lockout. Need to get the pH up more toward 6.4 - 6.5.

Thank you Straight808 and Muddy,

I've ordered a pH meter from Ozone World yesterday to have a better accuracy on my pH. I don't trust the soil meter, because it's reading 7.0 all the time in different soil types.

I'm on day 1 after feeding with BioBizz BioBloom, Heaven and Enzimes+ to fight against P defficiency. Redness of the stem rised up to third node and respective fan leafs stem. It was on 2nd node yesterday. A little brown burn on those fan leaf tips aswell.

Oldest leafs slowly starting to turn into a pale green.

I think this is normal, the plant needs a few days to show some adjustment after feeding.
