Update on my first grow...w/ pics...& questions

How's it going everyone. This has been my very first grow, and i have to say I thought it would be a lot harder, dont get me wrong, I had a few bumps in the beginning, but now i'm solid. The key to my success has been the PH pen i bought on ebay. The strand is bubblegum.

Here are some questions for some experienced growers. These two plants will be flowering for 5 weeks on Monday (July 3rd). Is there a time when these buds just start growing out of control? My main cola is huge w/ bud, but the rest of them are slacking a bit, and i'm wondering if they'll catch up or not. And by looking at my girls at this point, can someone give me a "rough" estimate at what i'm looking to harvest in terms of OZ's. I was hoping for 2 each plant, but what do i know? Should i be using another fertilizer? I'm just using Superthrive and Pure Blend Bloom at the moment.

Lastly, I'm using a 250 MH lamp, w/ a HPS conversion bulb running for the flowering stage. Is there any way i can get my bottom leaves to get more light? They're scrawny, and there are some budsites down there, and im thinking they're not developing because they're not getting enough light.

some cfl's maybe

using superthrive during flowering is not a good idea,try some liquid karma or floralicouse plus.if you want bigger buds you are going to have to step up to a bigger light,a 400 would work great.

Can someone confirm that superthrive is NOT a good idea for flowering? I dont know any better, but would like a second opinion.

I recommend getting some CFLs for some side lighting.. maybe two per plant.

What do you guys think of my first grow??????
