Chocolope Grow

Good afternoon,

I am new to this site and will be sharing some of my growing trials and tribulations as well as looking for advice.

I am currently growing a Chocolope plant this is about 57" and currently flowering under 4 - 4' 40 Watt Flourescent lamps using the warm 3400 Lumen bulbs. Temp is always at or about 72-76 degrees and I am growing in my closet for personal consumption. Closet is lined with Mylar and plant seems very healthy. Meduim is Organic soil...

1. If you think I should add or change bulbs please let me know.
2. My PH is down to 5.7 - Went to the Hydro store to pick up some PH up...Any other guidance would be appreciated.
3. A few lower large fan leaves have some brown discolorations and would like to know what the issue may be. Will share pics tomorrow.

I look forward to sharing and gaining knowledge from this site and it's members...

Until tomorrow...and enjoy the Photo's.
