Fluff buds in flowering

[SamRD]

It's been 5 weeks and 3 days and my buds are all fluff. Signs of N tox by curling down since like 2 days ago so I cut on N. There is growth but it's so minimal. pH, ppm, pests all ok. Single plant under ts1000.

Have you grown cannabis to full maturity before? What is your humidity? Cut nitrogen totally out at this point. I see possible heat stress as well. Is there air moving around the plant?

 

[drsaltzman]

Too much N.
Very leafy.
You didn’t mention nutes.

 

[SamRD]

35% humidity and between 23 to 28C temperature. Not much air movement no, could that alone cause fluff buds?

No I started growing this year and messed up my first crop in the unforgiving weather of the north that destroyed my plants.

too much nitrogen will hinder flower production during flowering

I'm feeding cal/mag, bloom nute and humboldts secret fert

 

[SamRD]

My N coming only from cal/mag, I already cut it today when I watered. I'm only giving a 1/3/4 bloom nute and the 0/0/2 fert

 

[go go kid]

not familiar with that brand of nute, is it a grow or bloom? only feed autos once or twice during entire life span with goodsoil

 

[drsaltzman]

Where did you cut N from?
Was your soil charged?

 

[drsaltzman]

My N coming only from cal/mag, I already cut it today when I watered. I'm only giving a 1/3/4 bloom nute and the 0/0/2 fert

OK, those ratios are fine. Cut back on amount.
What soil?

 

[SamRD]

Humboldts secret can be given all grow but it's more of a bloom nute, 0/0/2. It's not an auto it's a normal fem plant. The soil was that trash miracle gro moisture control, my first grow didn't know better. But it's been a long time, the slow release nutes ran out long ago. The cal/mag I'm giving is the sensi cal one, 4/0/0 I think that's the one causing the tox

 

[SamRD]

Thing is when I take it off the cal mag leaves gradually go yellow and die, my idea was to keep going until flush time and take it off and let the plant suck the leaves dry. It started getting tox just days ago, I think it reached a point it's rejecting the cal mag

 

[drsaltzman]

In that soil you have to be extremely light handed with your nutes.
My guess is that’s why they look the way they do.
Too much N.

I would use the the 1-3-4 and 0-0-2 half strength.
Maybe just water first.

 

[drsaltzman]

They’ll swell up.

 

[SamRD]

I'll do that, no more N, praying to the bud gods

 

[xtsho]

Genetics. Is that an auto?

 

[SamRD]

Genetics. Is that an auto?

No, it’s a blue dream fem from canuk seeds

Why are you giving cal mag at all? Are you using RO? Forgive me if you’ve already said. Too many responses to read through.
