Hindu Kush Buds taking forever because Nitrogen?

[Draws]

Hi there,

So I am growing Tweed's Bakerstreet Seeds (Hindu Kush) and I have had problems since the beginning, especially always running into Nitrogen Toxicity. I am growing 3 plants all started at the same time.

It's been 5 1/2 weeks of 12/12 light schedule but they took about 2 - 2 1/2 weeks to show their first pistils.
The picture below is the biggest of the 3 plants but it's also had the most issues.

15gal Canna Coco Coir Smart Pot with 40% Perlite (its a lot of medium i know)
Fed ~800-1000 ppm 2 gallons daily depending on my runoff the day before.

The actual Nutrients I use each feeding:
2gal water
Rhino Skin - 15ml (Recommended amount)
Voodoo Juice - 15ml (Recommended amount)
Sensizym - 15ml (Recommended amount)
Bud Candy - 15ml (Recommended amount)
Big Bud - 20ml-25ml (5ml-10ml over recommended)
5ml Advanced Nutrient Sensi Coco Bloom Part A - I just fed 5ml for the first time last night because of the constant "clawing" of sugarleaves / fan leaves (30ml is recommended)
10ml Advanced Nutrient Sensi Coco Bloom Part B (30ml is recommended)

During flowering I have been feeding 6.1-6.3 ph to increase Phosphorus / Potassium uptake

As mentioned above, the picture is the biggest plant, however, the one I have been admittedly neglecting a bit has much more formed 'Colas' already.

Also growing under Mars II 1600 LED (~700 actual watts at the wall) in a 4x4 area with an inline fan always pulling fresh air in due to negative pressure of exhausting outside. Temps are 25-26c lights on and 16-18c lights off with RH staying in 35% range, too much of a fluctuation?

I’ll bet the grow shop guy bought a new car after you left. You might consider dropping all that stuff except for your 2-part nute system.

Multi bottle madness is the problem

Why are you feeding Rhino Skin?

From the website:

"Grower’s Tip:
If you’re growing in coco, rockwool, aeroponics or any other “sterile” hydroponics method, a silica deficiency can weaken your crop, lower its potency and make it more susceptible to disease, insects and stress."

That's pure marketing garbage. $18 a liter. A joke.

Ingredients: Potassium Silicate.

Contains Non-Plant Food Ingredients:
1.0% Silicon (Si)

Damn. I bought a pound of water soluble 52.8% silica potassium silicate for $16. I can make hundreds of gallons of my own Rhino Skin for less than the cost of one liter. I used it on one grow and haven't used it since. Just something else you don't need to grow cannabis. But what a racket. I can't believe what they charge for mixing some inexpensive potassium silicate with water and putting it in a bottle with a picture of a Rhino on the label. It's like a 1000% markup or more. I'm not going to bother with the math.
How do people justify using all those products when the results are not that good? All the while people like me are getting excellent results using the same stuff they use to grow vegetables? Cannabis is just another plant. Treat it like one. Don't fall for all the marketing garbage from nutrient companies. All they care about is your money.

$16

I know someone who ran a scam where they had telemarketers call people and ask if they had a computer printer. If the answer was yes, they were asked the brand of the printer toner being used. Then the telemarketer would say "We have information that the kind you're using is radioactive. We can sell you non-radioactive toner for x-many dollars." People bought this story and they bought the toner. This made someone rich. Hydro nutes are the same thing.

Im not seeing N tox in your pics.
I wouldn't be worried at the moment, but would cut back 10-15% on nutrients.

I agree to a point but it depends on the nute's you're buying. You can buy hydro nutes all day long for a reasonable price. It's when the cannabis nute companies repackage the same thing and market it to naive cannabis growers. There are plenty of nutes for growing cannabis in hydro that are inexpensive and good. It's the slick markting for the same thing that some drink like koolaid that is the problem. $5 tomato fertilizer selling for $20. Same ingredients but with a cool looking label slapped on the bottle. Sucker born every minute.

Your plants look fine to me but you may want to simplify your feed regime

I'm going to have to respectfully disagree. 5 1/2 weeks into 12/12? Probably three weeks into showing first signs of flowering? Those flowers are stunted from too much nutrients/stuff. They should be much bigger. Nice big stems but we're growing flowers. People and their silica. I don't want big fact stems, I want flowers. That's why people buy stakes. To hold up the flowers that get big. Cannabis is just another flowering plant. Treat it as such. I have to stake some of my Dahlia's every summer. I guess I could worry about growing strong stems but that would take away from the beautiful flowers. That's why I stake them when they need it. I get Dahlia's almost a foot across. No silica.

Did I not say "simplify your feed regime"
The plant does look fine, other than small late showing flowers

I get tired of hearing about silica too. All these nonsense money wasters. People buy into everything and I’ll grow better plants with shit from the hardware store if I had to

I hope it works out for you. I’m a few weeks behind you with the same strain.
