Generally only use co2 if you're using HPS bulbs because of the amount of heat stress they put your plants under.

Co2 correlates with temperature not light conditions. 85-90 degrees F. 1200-1500 ppm co2

Harvest question. Amber showing up early.
The seeds I’m using stated a 9-10 week flowering period however I took a close look at some of the tricomes today and I’m seeing some significant amber colors and it’s only week 7 of flower. Is that normal? Do I need to rush and harvest them soon?

The plant is not having any issues yet but I was checking the runoff PH. It's going in at under 6 and coming out at 7+. Ec has been fine, no buildup. Could it be the buffers in the coco loco? Is this an issue I should be worried about?

Hello everyone, tell me your opinion, this baby is already 11 weeks old, but the bumps have just begun to form, is this development normal? I understand that it is still growing for at least 3-4 weeks?? And in what week do the buds begin to gain mass and volume ??

Harvest time
It's been around 8 weeks since flowering and to me the buds seem ready. However, these white pistils keep appearing and makes me think thank it's not ready. What do you think ? I also started watering just plain water, but i think i should go back to adding nutrients.
