Yip the smaller plants sometimes look better because they're growing not as fast and not requiring as much nutes. Ah well Dirty Bud roll on the next grow I say. I reckon from what you've learn't from this one, with the more perlite and higher nutes earlier on next time will be much better. See it just takes one thing to change (i.e. new improved more powerful lights) and it can throw everything off. Next time it will be dialled in a bit better. The time after that even more so. Keep taking records and notes and you'll be sorted mate
