Newbie - Greeting to all from Huntington Beach

Good afternoon members,

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 and I am going to the Hydro store to pick up some Lime...Any guidance would be appreciated.
3. A few lower large fan leaves have some spots and would like to know what the discloration is from. 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.

Jonny

Update - Went to the Hydro store and bought PH Up for the low PH...Look forward to posting pics of the discolored leaves tomorrow. BTW - I am at 3 weeks into flowering but growth was initailly stunted by about a week due to transplanting.

1 more quick question - Since my plant is tall would it be in my best interest to add another light vertically beside the plant with daily rotations? If so why would you advise to use as far as tubes? Warm, cool etc...

Thanks...

Here are the pics of the leaves...I wouls love some feedback.
