Airy buds in coco
Hello,
I just finished my second grow in coco. 18L pots, 70/30 coco perlite, watering once a day 2-2.5L until 20-30% runoff.
My first grow was in a tent, Vpd was tricky to keep good so I thought that was the cause.
Now I put them outside, painted my walls white, everything good so far.
VPD was optimal through all stages, no nutrient deficieisies, no nutrient burn, no toxicity, nothing. Everything was dialed in, but I still had no dense buds.
I did stress them a bit during their stretch as I removed the lower branches. But I didnt train all of the plants (i had 8), and those I didnt train also had airy buds.
I thinking watering may be the cause, I had no time to water them more frequently during the day.
