Ideally any lollipopping should be done before flowering, but some selective and well considered removal of the smallest flowers shouldn't impact your plant too much. After looking through your diary for this plant, I think you may have over done it with defoliation, causing your plant to being unable to produce enough energy for proper flower growth. At this stage you still have a fair way to go before harvest is close, another 4-6 weeks maybe, so you shouldn't bee too concerned with the smallish flowers just yet, but do not remove any more healthy green leaves, your plant needs every one of them to make the energy she needs for flower growth. Comparing your results to others is not really helpful, there will always be others with better results, just as there will be others with lesser results, there are just too many variables involved with cultivation to make comparisons fair. Also, with only one 150 watt light, your plant isn't exactly going to set any records.
Your plant still has much growing to do, so don't get too concerned yet, but give her her best chance to perform by not removing any more leaves, unless they are yellow, for by the time they are yellow, they have served their purpose.
Hope this helps,........
