Purple stalk and purple on parts of the leaves

[TriniHighGrade]

Please help me I don't believe it's the strain although I could be wrong. But I more feel it's ah deficiency, could someone help me identify what's going on. I'm growing in coco peat and perlite with gaia green 4-4-4, bat guano, and earthworm castings mixed in and finally watering with advance nutrients stalker stiffener, kelp and pH around 6.3-6.5. Help???

Welcome to 420, Trini! It's a pleasure to have you.

Purple? I see it.

The purple on the stalk is more than likely genetic. I have a couple strains that run with purple stalks. Especially when the light gets to them. It almost appears on mine like a case of sunburn. No ill effects seen on my plants with the purple stems and stalk.

The leaves? Leaves have a tendency to go on the purple side when temps can dip a bit low.

What is happening is the chlorophyll is leaving and being replaced with anthocyanins. This brings about the blue/purples we see in colder grows. In my opinion the anthocyanins also have a distinct flavor; grapey kinda.

What is your grow room temp at?

it looks like you might have some pest problem along with the off colour , see some dodgy specks on the left side leaves on the pic one , looks like mite damage , worth getting a good look at also

Replying to patient puffer
Thanks for having me buddy and I truly appreciate your reply. I'm growing gorilla zkittlez feminized under 1800 watt cobs daylight temps 82f n humidity 52%-55%. Night temps 73f-75f n humidity 45%. This is my last two weeks of veg then I'm switching to flowering. Thanks again

 

[NuttyProfessor]

make sure you treat for pests BEFORE flower , its very hard to treat once buds grow

Hey buddy thanks for the reply, the white specs you see is saw dust. Was doing ah little woodwork and ah little dust blew their way. I meant to dust them off . Thanks again

 

[NuttyProfessor]

ok sweet , but always do a good check before flower , i have been battling mites a long time for letting them get out of control , prevention is better than cure

 

[TriniHighGrade]

Thanks for the advice will keep in mind. So far so good...

I have one more pic to show. Can anybody identify what this is? This is on another plant same strain...

 

[NuttyProfessor]

need pics with no purple light in background, it looks like you have a few problems , cal/mag

take the plant and get a pic with it under a normal light with the plant ad pot showing

like this

It's saw dust you seeing on the leaves

was any lime added to the mix to buffer the ph , something tells me the soil is going to run hot and too acidic

You think I need cal mag because I started using advance nutrients cal mag. I only applied it once so far.

I am just awake and going to walk the dog , i am sure others will chime in soon , back in an hour or so

No lime added. I'm using coco peat and I think my pH was to high close to 6.7

 

[NuttyProfessor]

yes but peat is very acidic and in the 4s , bat guano can drop too to very low levels thats why i wondered

Fresh guano has a pH of 5.1–7.3, making it neutral or somewhat acidic. However, as it ages, the guano becomes strongly acidic, reaching pH levels of 2.7–4.1.

most peat base mixes use lime so the ph balance out , buffering

edit i answered to quick , my dog was melting my head to get out lol

so its coco perlite and amendments maybe just plain water for a couple of goes see how it goes i see a bit of burn but not much, small plants don't need much burn to have problems or lock outs . you need this sorted before even thinking of flowering .
the rust/gold stripe remind be of ph fluctuations ,

right im off again , be few hours until i get back ,
