They got 20/4 in veg and 12/12 in flower. Gonna plant seeds into pucks next time then straight into the Airpots...next run will be smoother than this so I'm hoping to get away with only 3 weeks veg. You should at least go 18/6 for 2-3 weeks, 12/12 from seed is great if you loads of plants to yield the same as 5 vegged plants...less plants means less hassle if you're caught.
EDIT: And if it was me I'd ALWAYS top my plants,more big buds,less popcorn.
