CO2.
Is it needed?
I've got a CO2 bag, that I can pierce holes in and hang in my grow tent.
This is my first ever grow. My aim is not, at this stage, to get the biggest buds. Simply to get ANY buds :)
Should I use the CO2 on this initial grow? Will it make a difference?
Yeah like others have said you need the proper PPM in your space with heavy hitting lights to benefit from the added CO2. Though honestly if you already have the CO2 bag hang it up for sure. It’s not hurting anyone and it’s better than nothing so why not hang it up?
But just know that unless you’re enclosed and running 1200 PPM of CO2 there really isn’t much benefit to it.
Honestly on first grow there’s a lot gonna be happening. I would focus on getting the fundamentals down before really starting to add an other factor like CO2 to the grow.
Anyway good luck with your grow 🤙
Scooby_Doo Two problems:
1. Naively, I used two different grow medium and now I have two radically different sized plants. I assume one will hit the budding phase sooner than the other, which will cause problems later on.
2. The leaves on both plants are off-colour. Are there missing a nutrient?

Scooby_Doo Plants seem to have recovered from last week's scare. I moved the light further away and fed them a general plant nutrient I had in the house. I've just bought a new specialised nutrient so will start feeding that this week.

Scooby_Doo Cut off a couple of the damaged leaves. Looking far healthier now. Not sure whether to keep watering or let them dry out a little

Scooby_Doo Days are getting cooler, which is reflected in the internal tent temperature. Do I need a heater? Plant leaves getting a light green colour on them. Is this normal. And when do I start flowering?

Scooby_Doo Leaves still look mottled going into flowering but the switch to canna coco feed seems to be stopping them getting worse. Hopefully leaves will return to normal in the next week

Scooby_Doo Does anyone know why they're not flowering, despite being on 12 hour light schedule?

Scooby_Doo Buds starting to appear on one plant but not the other, which is still growing lots of new leaves. How do I 'force' it to start flowering?
The other is far too tall and almost touching the light.
Next time, I'll be prepared with LST and HST.

Scooby_Doo Plants have grown so high they're almost touching the light, which is a problem.
Buds slowly appearing on one plant but the other is behind in its development

Scooby_Doo Buds are developing. How long do I leave them? How do I know when to harvest?

Scooby_Doo Plants are far too high for the tent. I can't raise the light any further so the top of the plants are almost touching the light.
Have these foxtailed?
Buds seem to be very fat apart rather than clumping together.
Pistils look brown so I've decreased light schedule to 11/13
Scooby_Doo Disappointing but a big learning curve. The plants hadn't pollinated but one plant didn't grow. The other got done buds along the stems but not much. Has an effect though, so that's something at least
Looking back at my diary, week 9 is when I should have HST'd the plant and somehow stopped it growing so tall. It's now overstretched and touching the LED light.
One of the plants was looking yellow. An experienced grower asked me what I was growing it in. "Coco". Not enough nutrients, he said. It needs feeding with every watering. So, I've started adding some Multi Zyme to every litre of water. After 1 day it's already picking up.
Man, you are using big bud coco wrong. It's only meant for the first 2 weeks of bloom. And it's clear your PH/lack of nutes is way off. I wouldn't put it down to C02, more of a lack of tools buddy. When growing in coco you gotta feed daily with every nute. So say I give 6 nutes to my plant, and I'm using coco, then you have to give them nutes everyday. And never use bud bloomers on veg, your asking for trouble, and 1 more thing. The way you have your pots In water, that's wrong, that will cause root rot and stunt your growth. If anything leave them in that tray, and put your pots on something and the roots will make their own way into the water. Hope this helps.
Hey man it's looking nice!
I would suggest to try achieving a lower cannopy trained towards building a cannopy that fits evenly in the footprint of the light; increasing yeilds.
It's looking really nice! Goodluck with your grow!
