I use SuperThrive about every other water. I would use it up til the last watering.

I was speaking of ENVIRONMENTAL STRESSES not chemical or internal stresses.

There is just so much data now that these plants produce more THC under these stresses...especially when being attacked by say.....

SPIDER MITES.

Anyone know of a good THC test kit? They gotta have something neat and handy to measure the percentage of it...
