AsNoriuanswered grow question 3 years ago I grow LSD myself, got freebies from FastBuds more than a year ago, it's the last strain to try out and I left her last only because very rarely I see good harvest from that strain, but when you taste it - any amount will bring you joy.
Don't panic, but if your target is a lot of weed, try to search other strains for next grow.
They look small at yours, my guess is 25-35 g with your Cobs is more than easy achievable.
Good luck !
