I'm having the same problem here man, Damn caterpillars eating everything up..killed 3 butterflies today hoping they didn't already leave their babies in my plants. I'm going to go pick up some Safer brand caterpillar killer as I was told its effective and safe to use up until around harvest. That and BT, which is also organic.
Plants are looking great though man, I got a few grape apes too man!
Oh and you wanna get rid of the caterpillars sooner than later, one of my plants might be ruined from them already, I pulled over 25 of those little fuckers off of my plant yesterday, they were eating the buds from the inside out and left their lil poops everywhere which seemed to rot the bud away...
Goodluck!
and this is now... 
the one in the back is grape ape, the 2 on the left are sweet tooth, and the one on the right is gdp. the sweet tooth and grape ape are about 4 1/2 feet tall.
still no buds. only few hairs.. more hairs on the small one on the bottom right.. ahhh.. only had about 2 seconds to snap a picture before my lens got all fogged up.. ha
Canna-loupe... (also in green house) 
Grape ape.. 
SWEEt tooth... 
theses little fuckers ate the shit out of the leaves! .. found four so far.. working on getting rid of them... any suggestions?
BT and Safer is what I have been using as well. Don't skip a treatment!
this is the grape ape... 
and this is my smallest plant... strain unkown... 
How much longer do you think the last plant has til harvest?
