Tiny / Small buds 6 weeks in - no issues

[BurntByFire]

Been 6 weeks since flip to 12/12
Doesn’t appear to be any issues. Leaves showing no signs of issues. RDWC buckets clean and roots are white and full. No mold or bugs, all indoors.

week 6 day 2 since flip

water temp: 68 deg
PH: 5.6
PPM: 800-1000
Humidity: 60% - Tryimg to
tent temp: 81 deg
Athena line nutes + purpinator
Running CO2 at 800ppm
Lights were at 1400ppfd and now at 1100ppfd
Strain: kens GDP

The buds are super tiny. Last time I seen buds this small was when I had hermie plants.
Is it possible this strain is slow and long?

they were eating 300ppm daily and have slowed to down to almost nothing. But looks like they are getting what they need as leaves aren’t showing any symptoms.

maybe turn off CO2 and turn lights to 900ppfd?
Maybe light stress?
Any thoughts

Overfed

Ditch the Purpinator.

Yep.. looks like youre abit high on nitrogen..
Those leaves look like they have nitrogen toxicity and you heve tip burns...
Far as them buds go,, some strains produce small buds..

I was thinking high ppfd
But you’re thinking too much food
I can ditch purpinator but 700ppm is borderline low, not sure I can reduce nutes by any more.
At week 6 I’m wondering if they’ll still plump up…

Which is weird because I’ve been using the PK at 1.5x the Bloom A and B which has zero nitrogen

Nitrogen is not the only nutrient that you can overfeed. The plant is pretty dark green but overuse of P/K can cause issues as well and stunt bud development.

I don't know the history of your feeding but the plants don't appear to have responded favorably.

You should have some nitrogen in there..

Buds will develop much bigger over the next few weeks - try bringing temp below 80F - adjust your PH to 5.8 is the sweet spot for me to 6 last week or so in flower.

More LIGHT = more buds .

Tops are considerably smaller then buds further down which is why I was thinking too much Ppfd

You want 800-1000 PPFD everywhere in your grow room, not just under the center of the lamp, anything above 1200 and you need CO2 or you're just wasting the extra energy, with CO2 going above 1500 is where it starts to become minimal what you get for the extra energy put in. These numbers are for getting the optimal light saturation and you can easily grow with a lot less light and have great results.
