The soil I'm using is an indoor potting soil that has a combination of slow release nutrients. Scott's and Schultz make very reliable soil mediums. Using this soil i don't need to give very much nutrient in the early stages of vegging. I do however start to give them a Shultz "5-30-5 Bloom Builder" in the last week of 18/6 and into the first few weeks of flowering(12/12) until they show signs of nute max out. It's a very heavy phosphate mix, ideal for Flowering.

As for the weight issue on the secondary growth...it can be a bit of a problem when your branches begin to bow under their own weight...
this is what string was invented for :smokin:

P.S.
Dry weight on the main cola taken as a sample from my smallest plant is 8.5grams.
Also, I've been asked to write up a FAQ on CFL lighting. This will help many of you who are so strongly interested in beginning with CFL lighting.

Thanks for all the support again guys. :dance:

Cheers,
Bob.
