Yellow Leafs.. Heat Stess?? CFL

[Rusty Trichome]

...about the yellow leaves since they most probably die... should i remove them so the plant doesnt wast energy in those leafs??

I just wait till they fall off at which time I remove them to prevent leaf litter. (bugs love leaf litter). The plant is sucking-out (removing) any remaining mobile elements and nutrients as the leaf dies.

ohh and about the soil i am using is Scotts Potting Soil,

I don't know where the heck I got Fox Farms Ocean Forest from. But regardless, it's along the same lines as Miracle Grow Organic or FFOF. Slow release organics. As with all peat-based mediums, ingoing ph should be in the 6.3 to 6.8 range. I'd still aim for the high-end of the ph range, as the ph will drop over time.
