ok i have 5 plants that are around 4 months old and have been budding for atleast 2 months....starting these plants was easy ....i used foxfarm organic soil with adv nutrients organic iguana juice under a 400 watt conv light......everything went well during veg and most of budding untill i noticed that around 2 months into budding my plants started to show less signs of growing nice fat buds instead i got really light fluffy weed that just doesnt seem to wanna finish up and fill out....... what can i do if anything to get my buds to thicken up and finish out
