Help me prevent a problem....

This is a first time grow, my two female plants look good and are just about in the second week of flowering. I would like to get as high a yield as possible.

The problem is, when I started, I did not know the things that I know now. I used Sta-Green potting soil with Moisture Max and time release nutes for up to 9 months. The Sta-Green composition is 14-11-8.

I just bought a basic soil test kit and my results are as follows:

1. pH- 7.0
2. Nitrogen- Medium
3. Potassium- High
4. Phosphorus- High

Are these levels okay? If not, what do I need to do to fix them?

The plants themselves look good. There is a little bit of yellowing to a few minor leaves at the bottom. Other than that, they're doing fine. I just bought some Green Light Root Stimulator 5-15-5.

I have been adding sugar every other watering and would like to start adding the Green Light, if you think it'll help bud production.

You could do a 3to1 flush with 6.5 ph water. then start flower nutes

I think those levels are ok, although probably better in weeks 3-6 than now. Dont know about plain sugar, most soil growers use molasses-black strap unsulphered
