Red steams on my plant???

[kaydeezee]

Hi, her is a few pictures of a original ammo 7 weeks into flower and I'm seeing some red through the veins of my leaves and also down the steam???
The steam's them selves are really stiff
Any ideas people????
Here is a list of the nutes and soil Im using.
Plagron light mix
Formulex
Rhyzotonic
Ionic grow bloom pkb
Calmag
Formulex was at half dose for first fee weeks of seedling to early veg.
Grow was at half strength 3ml per litre then was increased to 7ml per litre until the first week of flower.
Rhyzotonic for when I transplanted
Bloom at the same rate as the grow 3ml per then 7ml per
Pkb was introduced at week 5 at 1ml per litre once Weekley
And finally Calmag at 1ml per litre?? I was told to use Calmag because I'm using ked lights and they lack calcium &magnesium???

Here is a leaf with some fade yellow and red veins??
My ph is 6.8
My temp is 24.5c - 27c N /21c-24c
Light is a 140watt actual draw and my space is 1.5ftsq

A lot of different strains will develope purple/red stems during flower.. I don't see any problems or deficiency..
A little fading from the light in the very middle.. Looks like genetics..

 

[cheeseofchud]

its from a lack of nitrogen

 

[SPLFreak808]

Nitrogen a bit low, im assuming you cut it out completly so early on purpose?

The red stem looks like genetics

The fading tops look like a nutrient imbalance or possible lockout from too much p/k. You did notice the problem after boosting it yes?

 

[thenotsoesoteric]

Lack of nitrogen causes the yellowing the purpling of stems maybe cold temps or either P or K uptake is slacking.

 

[cheeseofchud]

red stems can be genetic,blueberry lines are known for this,i figured the yellow leaves plus red stems would be a nitrogen def though

but its not a bad thing,,,,4ish weeks from flip im guessing?

 

[kaydeezee]

So in order to sort this problem I may need to increase bloom & PKB???
I have only given her small amounts of feed due to the issues I was having but maybe I should start giving her a decent feed??

Thank guys

How many weeks left?

 

[kaydeezee]

Flipped her 7.5 week ago but she is a sativa dom and I think she might go 11/12weeks maybe more..
And I did notice this problem before I boosted her with PKB? I will do some experiments to find out what's going on?
One of you guys is right but wich one lol
Than for your help guys ....happy growing

 

[Urbz]

They are all right my friend. The yellowing leaves drooping at the bottom are due to N starvation. The red/purple stems seem to be genetic or temperature IMHO. The main stem at soil level is still green, with no apparent striping/streaking. Yellowing leaves at top are due to light saturation. At 60-70% of the way through flowering, nothing really "bad" is going on. Maybe add 1/4 strength veg nutes with you're normal feeding regime and back the light off a couple inches. Maybe, lol c

Good post I have never had red stems or light saturation issues. I learned something. Are you using C02? Gave 1 of my plants CO2 poisoning once leaf color was very similar. Although my plant was obviously ailing, yours seems to be only discolored.Veg fertz are higher Nitrogen. Would be interesting to see what would be results if you keep doing what you are doing and gave her some drinks of water + nitrogen only? Maybe ammonia and water.

thanks, was wondering why my blue dream bitch is red

 

[kaydeezee]

I just fed my ammo plant some veg nutes to bump up the nitrogen?? Fingers crossed that's the problem??
She does smell nice and she is forming some nice trichs so happy days
